BackupHDDVD may be this generations DeCSS

This article was first published on HWUpgrade.com

It hasn’t been completely verified yet, but a user named "muslix64" has posted an exploit in a thread on the Doom9 forum claiming he has been able to circumvent AACS, the encoding format used to protect HD DVD and Blu-ray content.

"Muslix64" claims to have completely backed up an HD DVD movie and provides a Rapidshare link to download BackupHDDVD, a small Java-based utility that aids users to backup their HD DVDs. A YouTube link to see the program in action has also been posted.

"Muslix64" describes the utility as "a java based command line utility that decrypt video files (.evo) from a HD DVD disk that you own, to your hard drive and you can play them back with a HD DVD player software."

Although much of the dirty work in backing up an HD DVD movie is done by the tool, users are still required to find their own cryptographic keys for the disc being copied. No guidance is provided to help users find the keys but the author suggests the process is trivial, which suggests some exploit in the player software or hardware exists as the keys are not meant to be easily obtained.

Although the exploit hasn’t been completely confirmed yet, if it turns out to be true it could mean a number of things. For one, it is possible that we might start seeing pirated HD DVD content. In addition, since Blu-ray also uses AACS, we might see a similar crack be released for Blu-ray movies in the next couple of weeks.

"Muslix64" claims the tool works on his XBOX 360 external HD DVD player, but that the software should not be limited to just one specific player.

The Keys are in the HDMI part of it, to stop you from watching HD content on a non protected tv, I read the spec, and it seems easy enough to fool. But the real problem with is is that all you need to make this worthless, is for a major LCD/Plasma TV manufacturer to have all its HDMI keys made public, that key is revoked, so the next time you buy a new HD-DVD, or use HD-Sky/or HD-Digital TV, it will dissable your HD content!!

I am supprised the manufacturers actually Agreed to this...

I would not be supprised if some rich people with a grudge against restrictions brought TV's, hacked them to get the keys and then published them... And its BYE BYE to the millions of TV's, they would have to be recalled, and some major lawsuits will unfold... I dont see Sony sitting back and loosing money due to a flawd system...

You are thinking of the keys for HDCP, which are completely different and separate (but possibly more annoying) than AACS.
