The AACS crack that wasn't: BackupHDDVD

I will give a little more detail on what we've learned about this hack and just how extensive it is. The short version is that HD DVD appears to have been compromised via a software player, but the compromise does not seem to be particularly robust. In fact, I'm not sure that calling this a "hack" or a "crack" is in any way appropriate. It's nothing akin to DeCSS or PlayFair, which are self-contained DRM/encryption strippers. By itself, BackupHDDVD is useless.
