From Professor Farber's IP List. Blu-ray and HD-DVD both cracked before they ever get a chance to grab market share? Maybe, read on for the details on how the AACS forum can strike back.

AACS Decryption Code Released
Monday January 8, 2007 by Ed Felten
Decryption software for AACS, the scheme used to encrypt content on
both next-gen DVD systems (HD-DVD and Blu-ray), was released recently
by an anonymous programmer called Muslix. His software, called
BackupHDDVD, is now available online. As shipped, it can decrypt
HD-DVDs (according to its author), but it could easily be adapted to
decrypt Blu-ray discs.
Commentary has been all over the map, with some calling this a
non-event and others seeing the death of AACS. Alex Halderman and I
have been thinking about this question, and we believe the right view
is that the software isn't a big deal by itself, but it is the first
step in the meltdown of AACS. We'll explain why in a series of blog
posts over the next several days.
Today I'll explain how the existing technology works: how AACS
encrypts the content on a disc, and what the BackupHDDVD software
does.
