The DRM "protecting" HD DVD and Blu-ray Disc films -- AACS -- continues to unravel at the seams. In parallel efforts, hackers in both the Xboxhacker and Doom9 forums have exposed the "Volume ID" for discs played on XBOX 360 HD DVD drives. Any inserted disc will play without first authenticating with AACS, even those with Volume IDs which have already been revoked by the AACS LA due to previous hacking efforts. Add the exposed processing keys and you can decrypt and backup your discs for playback on any device of your choosing. So yeah, it looks like last week's WinDVD update has been quickly and definitively made useless just as we expected it would be. Well, for XBOX 360 HD DVD drive owners anyway but you can see where this is heading, right? Now go ahead AACS LA, revoke the Toshiba-built XBOX 360 HD DVD player... we double-dog dare ya.
