untangling regional dvd restrictions

Overview

So in Windows and Mac, there’s this so-called regional settings that only “allows” you to change your regional settings five times before “locking” it in, courtesy of the entertainment industry determined to dictate every choice to their customers and squeeze every penny out of them into the bargain. Ah, the fresh smell of capitalism in the morning. ;-)

The way it works is that DVDs which are “Region 1″ (2, 3, etc) are CSS (content scramble system) encrypted. The settings on the computer indicate which “region” it is, and that will refuse to play those DVDs not matching the set region. This is a result of collusion between OS companies (eg, Microsoft, Apple), DVD drive companies (Panasonic, Sony, etc), and assorted software programs. It’s an ongoing legal tangle, and also when OpenSource is tossed in, gets interesting fast, as OpenSource will not generally “respect” the encryption and simply play DVDs regardless, although such a user generally will need to install a few extra programs and such to make it all work so in the end, everyone winds up having to work around this issue.

Oddly enough, it’s almost simpler when discussing DVD players. For these, just google up the brand name of the player, along with the terms ‘region free” etc, and it’s possible to find, for most players, the codes necessary to convert the player into multiregional or region free players. Once that’s done and it’s hooked up to the TV set, playing any DVD is not a problem.

Approaches

But back to DVD drives in computers: there are several ways around regional restrictions. One has been to hack the firmware on the DVD drive. This isn’t an especially good idea since such hacking can render the drive dead a certain percentage of time. So I’d toss that out.

A second option is to copy the DVD first, stripping out the CSS, and burning the altered copy to a blank disk and using that DVD instead. This works, but is a little cumbersome — having to copy each encrypted DVD before viewing it.

Finally, there are software programs that simply bypass the operating system restrictions. These can be built into the dvd players themselves, or be a separate program functioning on its own, allowing the user to use whichever favorite software for viewing the disc’s contents.

Windows

For Windows users, most of the options center around the third one, although a number include the ability to use the second approach as well. For example DVD Region + CSS Free and DVD Region Free Master (both very reasonably priced shareware). The programs work at the software level to bypass any restriction on the computer’s dvd drive, whether or not it has been locked (changed more than five times) and without altering its allowable changes.

DVD Shrink allows users to copy commercial dvds to blanks. The program allows for copying and compressing and/or eliminating parts of the original dvd, including stripping the CSS encryption.

Mac

For Mac users, the picture is a little different. There are some programs out there but there don’t seem to be that many (and which seem to be for older versions), which puzzles me because OSX is Linux based, more or less. Some of the issues seem to revolve around which Mac one has, and which dvd drivers it has. VLC may work for some Mac users, but does not work for all. I did find this article which summed up the issues for mac users and described one solution the author worked out. I have also seen speculation that Mac’s new Bootcamp software might allow Mac users to run the Windows region free software + dvd playback to obtain similar results (but I did not find anything written up by anyone who’d tried it to see).

There’s a program called MacTheRipper which allows copying of DVD’s minus the encryption. Also check out DVDBackup to back the DVD up on the computer.

Of course with the new Intel chips, a dual boot WinXP and mac, or dual boot with Linux and Mac and move back and forth as needed. :-D

Linux

As an Open Source operating system, Linux’s difficulties with CSS encryption stem from the proprietary nature of the software. In most cases, what a Linux user needs to do is download the additional software and codecs to view DVD’s. Most distributions will have instructions available somewhere on how to do this: googling on the distribution name and region free will in most cases uncover instructions specific to the distribution. For example, googling on “ubuntu dvd region free” (without the quotes) will uncover tutorials such as this.

There are a wide variety of players, such as mplayer, Xine, Kaffeine, Ogle, and Totem. Most distributions will come with one or more of these, the trick is enabling the play for encrypted DVDs as covered in the previous paragraph. Of these, Kaffeine is generally considered the best of the lot. The rest may not have a full gui interface, or sync properly, be somewhat buggy, or have other limitations.

As for creating region free DVD’s: one method is outlined here and another nice overview is here. The basic idea is as with the mac: create a copy or backup on the computer, and then burn selected portions to the blank disc.

Cross Platform

One name that kept popping up was VLC which has versions for Linux, Windows, and Mac. I have not tried this myself, but the user feedback/ratings look pretty good.

Legal Issues

Notes about legality. It’s becoming a bit more common to find notices such as this one even outside the U.S. Not only do laws vary from country to country but they appear to be in the process of changing, as more attention is paid to this issue. I should stress that this article is provided for informational purposes.

Also, I am not a lawyer, but this is my view: When I purchase a book, I am entitled to read it, whenever and whereever I want to. I can read it as many times as I want to. I can do anything to the book itself — write in it, tear pages out, laminate it, store it, throw it away, give it away, or sell it. I may not make copies of it, with the exception of small excerpts and such under “Fair Use” doctrine (eg, quoting passages in a review, that kind of thing). Extending that concept to a DVD, I personally find the encryption and regional restrictions problematic, as these may prevent me from enjoying something I have paid for the right to view. I therefore view getting around the encryption to be a legitimate exercise in being able to make rightful use of a product I’ve paid for.

The gray area is, obviously, when DVD’s are copied. And here it’s unclear: for example it’s been established as acceptable for users to make personal copies of audio tapes or CD’s — for example making a cassette tape for personal use, because one’s car does not have a CD player, or “timeshifting” where one makes a VHS copy of a broadcast to view later. No reselling is involved. So making a copy of a DVD for personal viewing ought to fall into similar categories (watch a DVD on laptop), but the companies are nervous because at this point, redistribution of copies is ridiculously easy over the Internet (not as easy to make VHS tape copies and distribute, nor audio cassette copies and distribute). That, in a nutshell, is why DVD copying is an “issue” and why the conventions are inconsistent between book, tape, and CD/DVD.

into the thickets of free software, open source, and personal privacy

Came across this article the other day and I’ve been thinking about it. Setting aside his somewhat confusing terminology (”Free Software” really should be called open source, because the very program he is railing against, Picasa, is free software. The source code is proprietary, but the software is still free…), he nevertheless touches on a number of issues I’ve been fascinated by for the last several years or so.

In any case, like any good geek, I’ve used freeware for years. Who wouldn’t? And of course I’ve always been generally aware of open source software, as anyone on Unix would be, through the efforts of gnu, linux and the like. However, since I was using Windows increasingly in my current job and lazily on my home computer, it wasn’t until about two years ago when I decided I was going to migrate to Linux and then last year when I completely removed the Windows installation that I was looking much more closely at Open Source.

We already know that the Open Source model is sound. There’s more than two decades worth of solid work, starting with the early GNU projects to today’s Linux distros and more to show that. What’s more, especially for the more popular and widely used programs, the churn rate on bug fixes and feature additions is much higher. You only have to look at Firefox’s quick turn around on bug fixes, and the number of releases its made as compared to Microsoft’s completely anemic Internet Explorer 6 which gets only a minor facelift some seven years later with the release of IE7.

But if you’re not compiling things, if you’re not poking through the code, if you’re happy using just executables, then the philosophical differences between freeware and open source aren’t going to be obvious. And certainly there’s quite a bit of other freeware that enjoy the same pace of responsiveness and bugfix/feature adding. Linux users, even while preaching the open source mantra, tend to rave as much about google software as anyone else, and last I checked, googleware, while free, is most certainly not open source.

There’s a slew of other considerations as well. Open source software is more likely than most to be present on multiple platforms. A good piece of software whose code is accessible can be ported by someone interested in it elsewhere. This simply doesn’t happen with proprietary code; only the owner of the code will make any necessary investment to do so, and many don’t. And the beauty of using the same program whether you’re on Windows, Mac, or Unix is that you don’t have to memorize new interfaces. You’re more likely to be able to interact without issues with someone on another computer. Send them a file and it will be correctly interpreted and opened. The frustration factor goes down and the usability factor goes up.

However, I think Picasa is a slightly different issue. The only reason Picasa is available on Linux is because it’s bundled with Wine, an open source program that allows Linux users to run Windows applications. Google made extensive fixes and extensions to Wine so that it would be able to run Picasa in Linux. We therefore have a piece of open source software which has been extensively upgraded in order for Picasa to make its Linux debut.

This actually takes the entire Picasa debate out of the usual free vs open domain, and indirectly brings me to another issue especially relevant with today’s issues on domestic surveillance by the governments: the final reason that pushed me over the edge into getting out of Windows was the whole DRM and privacy concerns. This involves not just the DVD protection stuff but also the trusted chip technology (blog of helios has a pretty good run down on this whole issue worth reading — check also for which hardware is involved). You’ll notice that now these trusted chip sets are going to be on Macintosh computers as well, with their well publicized move to Intel chips.

Linux is literally the only way out of this for the foreseable future, and it’s Open Source that will guarantee that. Even if DRM were somehow put into it, anyone could recompile without it. Folks outside the country could keep versions available.

And how did I come to this digression with Picasa? Back to Wine: it could well be a way for die-hard Windows users to get away from the DRM technology while still running the programs that they know and love. I just love the multiple levels of irony here.

cross platform and cross computer utilities…

In general, the programs and tools I use revolve around a couple of considerations:

  1. I need to use them at home/at work (or more precisely, from different computers)
  2. I want to use the same tool regardless of the operating system I’m using (I have linux at home, but must use Windows elsewhere)

Ideally I’d like my data accessible from anywhere, and I don’t want to have to learn new applications just because I’m on a different operating system. Obviously there are no hard and fast rules because some programs are just too useful not to have around even though they only run on Linux. (Don’t let the mentions of Linux scare anyone off here. Everything I discuss is either a web application or works on Windows as well as it does on Linux.)

In practice, this means I gravitate toward browser based utilities and open source cross platform utilities. In the former category are many of the Google tools: Gmail, Calendar, Notebook, plus others such as Bloglines, Meebo. In the latter category are Firefox, Thunderbird, Open Office, Gimp. Sometimes there are programs near and dear to my heart that I take the trouble to locate off platform versions of them, such as vi (yes I know I’m depraved) but this last category I’m not addressing here.

I’ve actually known about Meebo for some time, but I’ve started experimenting with it only in the last few days. I have no complaints whatsoever with Gaim which is what I normally use. However, when I was travelling for a few weeks last year, it was very cumbersome to download it, unpack it, use it, and then delete it. I should have made use of Meebo then although I’m not sure how usable it was at this point. Right now, it’s pretty sleek, works very well. Could use some more bells and whistles (I do not mean this literally in the sounds sections) — I have a hard time telling when I’ve got a new message in, for example. But it’s got a good interface, looks very smooth, and is worth checking out. It also offers a one stop place to log all your conversations, which could be a good thing or a scary thing, depending (completely configurable, never fear).

Feed aggregators have been interesting. There’s plenty of computerside clients, of course, but for this one I definitely want a web based one! Google Reader and Bloglines seem to be the main contenders out there. I tried Reader first, but it has an inherent disorganization that makes me want to scream. You get fed a steady stream of all the new articles that have come out. And if non has, no problem, it will show them to you over again. You wind up completely uncertain of what you’ve seen, where you’ve seen it or even when you’ve seen it. You lose all context since a post from that political blog might be followed by a post from that comics blog and then your little sister’s journal entry. No thanks. Yes, there’s kind of an edit subscription mode at the top you can turn on that helps organize the information, but there’s no settings to turn that on or anything. Bloglines is much better organized, although their frames setup makes me want to scream. They could set the sidebar up without frames, I’m sure, and make a much nicer interface. Still, the organization of the subscriptions into orderly files is wonderful, and they have several API’s for accessing the feed list which you can turn to nefarious purposes on your own website and so on. My particular favorite has been to assemble a comics folder, in which I placed all my comics subscriptions — rigorously selected to actually display the comic (some will just give you links to go to your comics — no thanks!) — and in the morning i just flip that folder on, go to wide view and jump down each one almost like a regular newspaper. I love it! And of course all I need is a browser and I can go thru my feeds.

Different web utilities can be combined in sometimes unexpected ways. Here’s one that’s proved very useful (via LifeHacker) if you use Google Calendar and you want to track the daily weather: Go to Weather Underground and find your zipcode or area of interest. When you get to the page in question, you’ll find a green ICAL link in the upper right hand area of the screen. Copy the link location for this ical file (in FF, right click and choose copy link location) and then go over to your Calendar, click on Settings, then Import Calendar and paste the ical address in there. What’s cool is that the next seven days or so have weather information in them, which gets updated. It cleans up after itself: the weather information is always eight days including yesterday. Plus, as the weather info updates during the day, the info box also updates in the calendar.

I’ve been using Delicious for several months now to collect my bookmarks in a completely accessible fashion, although I use DR’s delicious account more for “reporting back” here, so with that account I take the trouble to copy or type up some notes with each link. Either way, Delicious offers a way to access your bookmarks from anywhere, and through the different utilities and API’s that it has, you can do all kinds of stuff with the bookmarks you make, besides go searching or browsing through them at Delicious itself. They finally took the smart step of adding private entries to this utility, which is good for people who want to keep certain work links or personal links private and yet keep everything together. I experimented with Magnolia as well, which could be another alternative, but I have enough links on Delicious that exporting/importing isn’t an attractive proposition. Oh, and you can save an xml export of the Delicious bookmarks, although at present I don’t know of any utilities that work off of it (even Delicious itself!). Still, you can download that to your personal computer for backup.

The final sort of online utility I’ve been considering but have not actually used yet, is an online password saver. I’ve looked at this one, but I have serious reservations about saving passwords online. At the same time, if they are saved on my personal computer, I’m really screwed if I can’t remember something while away from my computer. (As an aside, I should note that I’m very strict about setting FF and other browsers and utilities to never remember passwords. Even if someone should get on the computers I actually use, they will find that nothing has my passwords: not my ftp or ssh utilities, not my browsers, nor my mail clients. Nothing logs in automatically and so on. Perhaps the constant need to remember my passwords will keep Alzheimers at bay, who knows…)

I don’t think I need to extoll the virtues of Firefox here, but it sure does have good extensions, which would make a post in of themselves. I’ll confine myself to the latest one I’ve nabbed: the copy as html link firefox extension which is a boon to bloggers everywhere (along with Google Notebook) in cutting and pasting links (how often have you copied the address, come back here, pasted it, gone back, copied the title, back here, paste, and so on ad infinitum?). With this, you highlight the text you want, right click, choose the copy as html that is now present, and go back to paste in one step. This is one of those tiny little utilities that fix something which was truly headdesking and yet never addressed till now and you wonder why it wasn’t done this way to begin with. This is functionality that should be built into browsers.

Thunderbird is a very well thought out program, and I do like how it’s set up. However, while it meets my criteria for operating across different platforms it still renders my mail inaccessible if I download mail with it onto a particular computer. So although I prefer its interface to Gmail’s, I primarily use it to retrieve and archive my email, from Gmail and IMAP clients (had to leave the pop ones alone). Still, if you use something like Outlook (shudder), you should definitely be looking at something like this. Plus, Thunderbird also has cool extensions like Firefox does, to help you customize it exactly the way you want.

I was initially somewhat dubious of Open Office’s Write as I’d tried converting a few files a couple years back and had too much trouble with tables, but the OOo team seems to have been hard at work and I’ve been very pleased with the results this time around. No trouble with any of my files so far. Ditto Gimp — I coudln’t figure out how to do anything the first go around, and this time I transitioned right off Photoshop with nary a hiccup. I’m particularly pleased that the interfaces on the Windows version are the same as in Linux. Saves me a lot of bother. Plus which the applications are smaller, faster, and somewhat cheaper than the Windows counterparts ;-) Even if you’re not a Linux user, you’d probably be pleasantly surprised at the speed and ease of use of these programs. They keep getting cast in terms of substitutes for Windows programs, but in reality they’re full fledged programs with a good deal more functionality plus interoperability.

If you’re not off internet cafe hopping, Gaim’s a great application. It combines all the major IM interfaces into a single program. Yahoo IM, AIM, Jabber (which hooks up to Gtalk), and others are all represented here. You don’t have to have multiple programs running if you’re talking with people on different IM’s. It’s got a slick interface, tabbed conversations, and it can do group chats as well.

There. That should be plenty of toys to look over…
