First Blu-Ray/HD-DVD key revoked
Due to the revocation, WinDVD users must upgrade to a new version -- containing a new key -- if they want to watch the HD-DVD's they own.
DeCSS rendered useless the entire CSS system on first gen DVD's, making copying, ripping and backups a trivial procedure. So far, the AACS equivalent remains elusive. However, you can bet that someone somewhere is hard at work on a way to compromise AACS again, either in a short term single key crack -- like the one we've seen here -- or a longer term, system wide crack. There isn't a single known DRM system worth cracking that hasn't been cracked, multiple times; AACS will likely be no different.
