DVD-Audio's CPPM Circumvented

Bodysurf writes "After DVD-Video's CSS encryption was broken in 1999, the music industry chose a much more secure copy-protection method for DVD-Audio called Copy Protection for PreRecorded Media (CPPM). This protection scheme has remained publicly uncracked, but it was circumvented recently, providing the ability to save the unencrypted digital audio data. CDFreaks has the details."
