Work Around for New DVD Format Protections

Posted by ryuzaki0 on from the oops dept.

An anonymous reader writes "For the new Blu-ray and HD-DVD formats, Hollywood implemented a complete copy protection scheme; almost everything has to be encrypted and authenticated. Despite the crypto-stuff in Advanced Access Content System and High Bandwidth Digital Content Protection, they left the backdoor wide open — they forgot about the PrintScreen button. Using this function you can create exact digital copies of a film picture-by-picture and reassemble them into a stream."

    You could just hook up your DVD player to a VHS recorder. Ever think of that?

    30 frames/sec * 60 seconds/minute * 150 minute movie = 135000 pictures, no? That's an awful lot of times pushing the print screen button. Even if you can "print" to an image file, and use a script to "push" the button continuously, once you factor in reassembling it, that'll still take a while.

      The wonders of hacking. If the print screen button works and it sends it to a file, hardware hackers will find what the button calles and call that directly. Then they find the location,software that does the final dump. That way they can avoing hitting the button and probably in 3 or 4 hours they can get a perfect backup.

      If something is so important that you feel the need to post it on the internet... It probably isn't that important.

    do you really think it would be that hard to create a program to do this for you?

    Ooh, can I make the obvious comment?

    Oh boy, I can't wait until the MPAA takes away my PRINT SCREEN key!

    thats quite a bit of work to copy a movie

    That's quite an understatement when you do the math: Avg. movie length of 100 minutes * frame rate 24 fps = 144,000 screen caps

    Who would even consider doing that? You'd have carpal tunnel in no time and pay more in medical bills than you would if you just bought used copies of the movies.

    FYI, doing the full extended editions of LoTR would be 982,080 screen caps!!!! Nope, not worth it.
