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 6.4.0.0 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.

Not a fan of your choice of words, but yes. I do like the idea of storing HD movies on a server and streaming them about the house. So long as they continue to drag their feet with the fair-use copy scheme, I guess methods like this will be necessary.

I don't think there is anything else that anyone could have said that would have done a better job at describing the situation that just simply saying "raped". Well done OP.

I couldn't agree more. I purposely built my file server and coupled it with XBMC for this purpose. (Ya I know the original won't play HD) With a 5 and 2 year old running around I don't have to worry about the disc I buy. They are opened long enough to be ripped and then put away. When the time comes for all HD content and the 360 finally get owned all the better.

Microsoft will be happy again, now you can do more than just watch Blu-ray with your PC. You can 'back-it-up', stream it, soon even modify it...

What does the 360 have to do with BD getting cracked? You lost me there.

I think he's saying that right now he's still using his original XBOX Media Center (?) for playing ripped SD movies since he's still not on HD. Once he moves to HD, that's when he'll get a 360.

You can stream HD content over a network from a server to your entertainment system via the 360. Ripping HD-DVDs and BDs to MPEG-4 or WMV-VC1 files will work this way. You save wear and tear on your discs and have the added convenience of simply selecting your movie by name in a list and pressing "play". Great for kids and a very high WAF (Wife Approval Factor - a necessary component of any home theater).
