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.

that kind of defeats the point of HD...

How so? I thought "the [main] point of HD" was the increased resolution, which would not be sacrificed by transcoding to a medium with increased efficiency of video storage. Sure there would be compression artifacts, but that case is no different than when transcoding DVD, or even having the studio author the release -- all three video standards used for HD media are lossy.

Now I certainly wouldn't use AutoGK, and probably not AVI, if I wanted to maintain optimal fidelity, but that is a whole other discussion.

NOT AT ALL.
You can get HD resolution content right now if you know where to look (Terminator 2 runs in at something over 15 Gigs.) And, compressed HD content looks absolutely fantastic - assuming you actually have a display source which plays at 1080p - and not just something that claims to be "HD." Also, of course, the encoder has to know what they're doing.

Remember compression was toted by the respective companies as an alternative to the DVD format war. Not that I agree with that, but you can definitely shave off Gigs of file-size without any loss in quality - IMO at least. Until High-capacity burners come out, unless you have a dearth of hard disk space, I don't know what you would do with a full DVD - or even compressed Full DVD at the kind of file sizes that result.

On the issue of "revocable keys": once the DVD is ripped there is a myriad of things you can do to it so that you'll never have to worry about keys. Further, once a disc is burnt and distributed how can they revoke and change a key that is hard written to a disc? And, who honestly cares that much about additional content, which could all theoretically be ripped to compressed file formats and distributed separately? I'm sure someone could even patch a release with the newest features if they wanted to take the time to do it.

Piracy is definitely the winner! But remember: as long as I can watch it, I can record it. You can't stop that fundamental truth.

Seen the 22 gig Gladiator? Hard drives are cheap and my GT6600 runs my Sony 34XS955, the CRT HDTV bomb, pretty well ;).

Hard drives may be cheap, but I have well over 1,000 DVD movies now...and a slowly growing collection of HD-DVDs. Good luck fitting that all on disk.

There are only a few movies I'll watch so I just don't understand a 1000 ;).

I'm hoovering up HD documentrys at an alarming rate however. I can double my .8 terrabyte array for under $400 which is not much really.

Why? Divx and other codecs have HD settings. Yes the file is still going to be big but you can get it smaller than the raw size.
