Dunno if anyone knew (apparently people did not), but a story that it was possible--via memory hack discovered from Dec. 2006-2007 by a user named muslix64--to obtain the volume keys of both standard HD DVDs and Sony Blu-Ray discs has recently created a buzz on digg, so much, that content providers threatened to sue the site if the (5 month old) story wasn't removed!

Details about the decryption are. . .

For those just joining us.....
According to AACS specs there are 3 keys required to decrypt an HD-DVD (or blue-ray since they use the same encryption specs):
1) A device key (from the player)
2) A volume key (from the disc)
3) A number of title keys (from the disc)
It goes in that order as well. When you first put the disc in the player it uses its device key (#1) to obtain the volume key (#2). It then uses the volume key to decrypt any title key (#3) corresponding to the title that you want to play.
