A programmer going on by the name muslix64 has posted a Java-based application that will free the encrypted video from its protection.
HD-DVD uses the AACS copy-protection system to encode content. AACS stands for Advanced Access Content System, uses two keys – a title key and a player key. The discs are designed with several player keys on them in a hash with title keys, providing an encryption algorithm.
According to a post on a Doom9 forum, muslix64 published an open-source Java application called BackupHDDVD that searches the computer memory for the movie’s key and decrypts the movie right off of the EVO files.
