One advantage that backers of Blu-ray have touted in the format battle with HD DVD is its extra helping of "unbreakable" DRM called BD+. It's not unbreakable after all. SlySoft, makers of AnyDVD, have released a new beta of their AnyDVD HD disc ripping application that it claims can successfully crack and rip Blu-ray discs protected by BD+.

That didn't take long. Just last week the company said that a crack was imminent, with full support for decrypting discs with BD+ protection coming by the end of the year.

According to a SlySoft employee's post in the company forums, the AnyDVD 6.1.9.6 beta has full support for playback of Blu-ray discs with BD+. "All available BD+ titles can be copied with AnyDVD ripper, or can be watched on HTPC without HDCP using PowerDVD 3104 and AnyDVD," reads Tom's post.

Finalized in June 2007, BD+ uses a small virtual machine that launches when a Blu-ray disc is inserted and runs in the background while the disc is playing in order to keep the disc's content locked down. If it finds evidence of tampering or copying, playback can be disabled. The code is specific to each disc, which is intended to make it more difficult to crack, and is erased from memory once the disc is ejected. The end result is an additional layer of protection in addition to the AACS encryption used by both Blu-ray and HD DVD, which was cracked back in April.
