A next-generation DVD security group has responded to hack attacks that allow unfettered access to Blu-Ray and HD-DVD content by pulling the encryption keys of PC applications associated with the attack. The move makes it impossible to play newly released high-definition movies via versions of playback software, including versions of Intervideo WinDVD 8, known to be weak or flawed. WinDVD 8 users need to update their software, closing the security hole and obtaining fresh encryption keys in the process.

Update: 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 Any inserted disc will play without first authenticating with AACS, even those with Volume IDs which have already been revoked by the AACS LA due to previous hacking efforts.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 I expected it would be.  Yeah, they can patch and patch, but hacks and exploits _will_ be found. No code is perfect :-)
