Latest Blu-ray Disc copy protection circumvented by PC software

Although Hollywood movie studios have little choice in which format they release their high-definition content, companies such as Disney and Fox chose Blu-ray Disc for its added copy protection features.

Since the AACS copy protection scheme was defeated, Blu-ray Disc had BD Plus (BD+), launched in June 2007 as a secondary protection method.

Like any other software protection scheme, however, it was only a matter of time before BD+ would be circumvented. In the latest version of SlySoft AnyDVD HD, released on Wednesday, the top new feature notes that the software can now remove the BD protection from Blu-ray Discs. The release note also mentions that the removal of BD+ increases compatibility with titles released by Twentieth Century Fox.

Effectively an embedded virtual machine inside player hardware, BD+ allows content providers to include executables on Blu-ray Discs to perform specific, content protecting functions. For example, the BD+ virtual machine could run diagnostics on the host environment to see if the disc player has been modified, or to verify that the keys have not been changed.

As part of the BD+ scheme, video may be deliberately corrupted or modified to prevent the ripping of the data stream for piracy purposes. The BD+ environment, once verified, will correct and descramble the content to render it viewable.

Thank you, what everyone forgets is that, BD+ is like a rolling encryption technology, it will be ever rolling and changing. So it might be able to crack it, but you will have to take time to look for the updates. I wonder who has more money and time on their hands to encrypt and break then system...

DVD DRM is still changing even though CSS has been fully reverse engineered for almost a decade. Slysoft manages to stay on top of new DRM schemes for DVDs. There is no reason to believe they or someone else won't be able to do the same thing.

AACS is also a rolling DRM technology. The problem with BD+ is that once it is broken, you don't even have to deal with AACS since BD+ has direct access to the unencrypted content.
