If you believe muslix64, a user on 'forum.doom.9', then HD DVD can also be cracked. He claims that his new BackupHDDVD tool decrypts and dismantles AACS (Advanced Access Content System) on a Windows PC. BackupHDDVD is a tool to decrypt a AACS protected movie that you own, so you can play it back later using HDDVD player software. Just enter a cryptographic key, and then you can back up your HD DVD movie right on the hard drive.
