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 126.96.36.199
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.

quote: Lol, not so fast there champ.BD+ was implemented with the thought of it inevitably being cracked. You'll have to circumvent the BR hardware to get any real use out of this exploit.
