New Copy Protection to Make Playing DVDs on a PC Difficult 557
The Cowardly Pirate writes "ZDNet's Hardware 2.0 blog is reporting that new copy-protection software for DVD publishers from a company called ProtectDisc not only makes it difficult to rip movies that you've purchased but also prevents discs from playing in a Windows PC at all. From the article: 'Protect DVD-Video is the brainchild of a company called ProtectDisc. Part of the copy-protection mechanism is a non-standard UDF (Universal Disc Format) file system which results in the IFO file on the DVD (this is the file responsible for storing information on chapters, subtitles and audio tracks) appearing to the PC as being zero bytes long.'"

Your average haxxor-d00d/bright-linux-guy/anyone-with-a-clue plays on on some other player that has been hacked up to deal with the non-standard UDF. It works fine.
Then his buddy, Joe, asks him for a copy since he had to return his 'defective' DVD. And while he's at it, he posts a torrent of it in case anyone else had the same problem.
So the studios end up pissing off and alienating their current customers who are unlikely to be pirating or copying the movie, while anyone who is already inclined to pirate/copy it still has the means and knowledge to do so (and now also has the motivation!). Really dumb.

How this works (Score:5, Insightful)
For the DVD-Video spec, the actual file system being used is irrelevant and is mainly used to "boot" the disc and discover where the very first data sector is located at on the DVD disc. From then on, at least in theory, all of the navigation to the rest of the DVD media is handled internally within the DVD-Video files themselves, including the MPEG data, as the navigation within the video data is handled with the use of special navigation packets.
So for a set-top box on your home television, the data scanners ignore the UTF file format and just march through the data according to the DVD-Video specs, not even aware that there might be a problem. Besides, these set-top boxes have just enough of a file system BIOS just to get to the "root" sector and not much more. Sometimes the "higher-end" ones will try to scan for MP3s or other kinds of media files, but that is a bonus and not required for playing the video data itself.
As for PCs, the operating systems are obviously designed to trust in the file system to believe that what the file system is telling you is also correct. Obviously you can mess with the order of the files and make something playable only on PCs and not set-top boxes, but usually you are more worried about the set-top ones rather than some hobbiest with some DVD playback software. The PC-based DVD-Video playback software is usually designed to trust in the file system and does the file requests through normal OS-related file requests rather than doing low-level sector navigation. This is a sign of good programming, not the lack thereof.
What is being done here is a very cheap hack that took the brains of a half-competent software engineering intern who knows just enough about the specs to get him/herself into some serious trouble and doesn't know the basics of trying to stick with known standards. Or to understand the need for redundant systems to try and protect data through multiple means of accessing the information. As has been pointed out, by doing this the file system is essentially corrupted, so normal OS file system requests will not be able to retrieve the data, unless you are accessing information on the DVD drive via individual sector requests instead (that would be the "hack" to break this "encryption" system). BTW, the "file size" of the IFO files is also recorded in the IFO file format itself as well, so "recreating" the IFO files is trivial in this situation if you can access the individual sectors.
I certainly hope that this idiot who designed this system didn't get a patent on the subject. I will go down right now as somebody to contact if you want to break the patent to testify that this is not a patentable idea in the first place. And as has been pointed out by others, this is clearly in violation of the DVD-Video standards and as such you can't claim compatability to DVD-Video by using this system. This is not a copy protection scheme but rather a corruption of the file system, as has been pointed out, and taking on a percieved weakness in the organization of the DVD-Video format.

Second, I hope I don't sound like a snob or something. I buy DVD's and have CD's. I'm just saying, my opinion is that, to me, they aren't "artists." They're more akin to a service provider. It's a business.
An artist can charge for their wares, but by working under the banner of a giant corporation with a contract that says "You must produce x amount of work over y period of time." that isn't producing "true art" by my definition. That's no different than doing what a manager tells you to for any other company. That's a job.
Art is more akin to science. It should be created for the pleasure, the interest and the mystique of thinking of new things, ideas, and the interest in sharing them.
Can you charge for it? Sure. If you make something people want to pay for, then by all means.
And the argument that "These people are screwed by **AA's and just trying to survive..." Fuck, I will bet dollars to donuts that most groups you hear on Clear Channel, see on MTV and who are prominently displayed up front at Best Buy just want lots of money. A lot of them even say it outloud. They aren't artists. At least not in my opinion. They entertain for a fee. They sell a service produced to generate the most income.

Re:How this works (Score:3, Insightful)
As far as making a workaround, all that is needed is to do the sector-level reading as an option if the IFO file doesn't seem to be loading properly. It mucks up the code a little bit, but it doesn't have to be in a time critical section as the logic would only apply in error trapping subroutines anyway. The non-trivial aspect is trying to make sure that the playback software routines can abstract to both data access systems and are not dependent on specific file access subroutines.
A custom "ripper" on the other hand would only need to read the sectors off of the DVD disc and "recreate" the files directly from the sector reads. Then you could re-burn the DVD with the "correct" file format as a very trivial exercise.
As has been said by others, this only screws up legitimate users who have paid for a legitimate copy of the content. It doesn't do anything to hurt the real mega-pirates who rake in the bucks reselling copied content. Very few people are willing to "donate" the bandwidth necessary for hundreds of DVD-quality downloads on a public webserver. And this is but a minor speed bump for hardcore pirates, including the amature variety.

No, it's all the tired 'n trite MTV bullshit of "we're only in it for the music" crap when any artist will tell you that while they do it for the love of their art they have lives and bills and obligations and aspirations beyond a life flogging their wares every night.
Furthermore there is more to art & performance then a guitar and drum kit and a whiny skinny 20-something pretending to be world weary. There is orchestra and dance and theater and film and sculpture, and those involve specialized venues and contracts and grants and workshops and all the rest, they're not just "Hey let's get the scooby gang in the van and do a 12 city roadtrip! We'll pay for it out of T-shirt sales, screw the recording rights!".
No, some art is not going to be out on the road every night, some art is ephemerial or specialized.

Oh, and lastly, being entertaining is not demeaning. Yes, it not every artist's goal, but many an artist does want to reach their audience through entertainment and to disdain such as merely populist and somehow lesser is nothing more then a profoundly ignorant (pathetic, really) attempt at snobbishness.

Big big big clue stick: There are other forms of art then "the band".
Even musical art.
Most towns of any size are home to a number of non-rock-act artists. We call them classical musicians, jazz musicians, studio musicians, folk musicians, choral singers, barbershop quartets, harpists, pianists, chanteuses, etc. And those are just in music, there are legions more in other performing arts, including ones with audio recordings (ever hear of a showtune? An opera? A bell performance?)
Some of these folks, and the organizations that they work through, depend on recording royalties. For some no recording royalties would likely mean shutting down.
For a concrete example that was the subject at dinner tonight let's take the world famous Boston Pops. They're made up of Boston-area musicians, including some from the Boston Symphony Orchestra, performing when the BSO isn't in season. They perform for hire, they perform in ticketed performances, they also perform free concerts. Much of their funding comes from, you guessed it, a large recording catalogue. Yes, all of those copies of "The Boston Pops Sing Your Holiday Favorites, Yet Again" add up, and give them a reliable revenue stream to build from.
Guess what? Some of us like their music. The Boston Pops do try lots of interesting things. Sometimes it is gimmicky, sometimes it is inspired. The same is true for classic and popular classical groups in many, many cities & towns. They are contributing mightily to the musical culture and just because they're not performing in grotty clubs to an audience terrified their musical heros-du-jure have somehow 'sold out', become less 'real', less 'street' (or whatever today's legitimacy criteria are) doesn't make them any less worthy of support.
(Oh hey, my house sytem just popped up the Boston Gay Men's Chorus performing Howard Arlen [bgmc.org] - great voices, great performance, fantastic material! Gonna argue that is any less art then Nirvana?)
This is true for many acts. They can't tour all the time, indeed their touring may be impossible or economically improbable but they can make great recordings and get them out there, use those funds to stage further performances, and continue the cycle.
For these folks the cliche pop/rock/rap-act-narcissistic answer of "tour" doesn't work. All it says is that the advocate for such has a tragically limited understanding of art and music and is unable, or unwilling, to see beyond their justifications.
So next time, before parroting again how musical artists et al are getting a raw deal, stop for a moment and consider that the artists you are referring to don't necessarily represent the entirety of musical arts. And so when actively or tacitly supporting minor acts of "fighting the man" consider that you may well be also hurting other musical artists, ones who have worked just as hard and just as long in their fields, and with their own families and rents and medical bills to pay.
