DVD-Audio's CPPM Circumvented

Posted by timothy on from the everything-that-rises-must-converge dept.

Bodysurf writes "After DVD-Video's CSS encryption was broken in 1999, the music industry chose a much more secure copy-protection method for DVD-Audio called Copy Protection for PreRecorded Media (CPPM). This protection scheme has remained publicly uncracked, but it was circumvented recently, providing the ability to save the unencrypted digital audio data. CDFreaks has the details."

      I think I'd rather wait for them to figure it out. It's not like I can't find plenty of other *gasp* decent artists to listen to without RIAA's hands in it.

      I know it gets thrown around in here a lot, but if you really wanted to piss them off and make them think about what they are doing, STOP BUYING THEIR CRAP. But more than that, don't download it either. Embargo them on all fronts. Watch them adapt or die. Too bad I'll never see this happen, what with the majority of my country (and apparently the world) being led around by the short and danglies by the RIAA. Like bands don't exist unless they have massive media hype, a video on MTV, and a shamelessly promoted 'world tour'.

      Makes me want to start my own music distribution just to show it can be done without the RIAA.

      'The Buggles' said it best:

      "Video killed the radio star."

      It's hard to find good music these days by listening to the radio, because they're just playing the tracks that look good on television. Flashy women or six-packed men appeal to the audience that the MTV or HMV bosses can make money from; but they can't play well, and they can't sing well. Hell, even Robbie Williams is a second rate singer, both as part of "Take That" and as a solo singer.

      "You can't see tits on the radio", but that won't stop people buying Kylie Minogue, or whoever is the latest fashion in pop, because that's what it is: Music is fashion. Gucci, Niki, et al make a fortune selling tat, but they make money because they're "fashionable".

      French Connection get away with selling - in the UK - t-shirts saying "FCUK - you" to 10 year old kids, because it's fashionable.

      No one cares about music, no one even cares what ten year old kids have plastered to their chests, so long as it's fashionable.

      How do you stop it being fashionable? That is the question. A few thousand people not buying the 'Crazy Frog' single won't make one iota of difference so long as it remains fashionable. Stop the RIAA, and the BPA's records, and their stars being fashionable, and perhaps you have a chance.

      But how do you do that?

  4. they can opt out of this arms race by milktoastman · · Score: 5, Insightful

    I know this fight against the Man is so very romantic, but the companies can opt out of this arms race in which the hackers have the advantage. The more and more this encryption breaking is done, the industry will spend less and less money on developing new encryption schemes, and instead spend more and more on buying Senators and Representatives to pass draconian measures to prevent you from legally trying (thinking about how) to break the schemes.

  5. Why DRM is doomed to fail by naich · · Score: 5, Insightful
    So, rather than try to compromise the DVD-Audio's encryption itself, someone has succeeded in making a patch that uses WinDVD to perform the decryption and playback, but instead pipes the decrypted audio output to the hard drive instead of the sound card.
    It goes back to the old adage; if you can hear it you can copy it. DRM is ultimately doomed to failure. The money spent on trying to implement a doomed technology would be better spent on setting up a syetem were it's not needed.
  6. Re:Slashdotted already? by Sycraft-fu · · Score: 5, Insightful

    That's what always cracked me up about the RIAA's parinoia over DVD-A. They burdened it with protections, set it so you can't get the full signal over a digital connection, etc. Why? Internet copying. Of course it seems the majority of Internet copying is 128k or less MP3s, often reencoded form another compressed format and/or recorded from an analogue line in.

    The people who trade that kind of stuff are not going to bother sending DVD Audio around. I mean it is on the order of 50MB per MINUTE compressed.

    The kind of people who have the money for a system that you can appreciate the extra detail on aren't going to squabble much about buying the discs.

  7. Re:The DMCA is a law by Arcane_Rhino · · Score: 5, Insightful

    You are being somewhat selective in your civic values.

    I do not think so. As someone who worked as a Customs Inspector for almost a decade and seized many many hardware and software components under the DMCA, I have a keen understanding of the intention and use of the DMCA. It was implemented with the intention of curbing the flow of violative software and the hardware that enabled use of illegal software. It also enabled businesses to better control their marketing districts.

    Preventing consumers from fair use activities was never part of the stated reason for the legislation nor were we ever instructed during our briefings to look for articles that would prevent consumers from manipulating legitimate (legally obtained and distributed) software and hardware.

    My background stated, I will also assert that I have no problem putting copyright violators in jail or with the seizure of illegally produced and distributed works. I am not advocating any type of free-for-all. I believe people should be fairly compensated for their efforts.

    However,
    since my time as an Inspector, I have observe many businesses try to warp the usage of the DMCA to their own ends. And not just the usual targets of /. dislike: My favorite was the court decision that third-party garage door openers are NOT a violation of the DMCA because Congress never intended the DMCA to limit consumer options. Good ruling but this is why I have become cynical about the current usage of the DMCA. It is no longer being applied to the "bad guys" but instead is being increasingly used by corporations to lock consumers out of their rights and choices.

    The manipulation of the DMCA in effort to extort more money out of the consumer or monopolistically control the consumer is unacceptable and unethical.

    I stand by my previous statement.
