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.

Still a game of cat and mouse...

From the press release at http://forum.slysoft.com/showthread.php?t=14786:

We are rather proud to have brought back to earth the highly-praised and previously "unbreakable" BD+. However, we must also admit that the Blu-ray titles released up to now have not fully exploited the possibilities of BD+. Future releases will undoubtedly have a modified and more polished BD+ protection, but we are well prepared for this and await the coming developments rather relaxed".

Looks like, unlike with DVD, BD+ will be a moving target, forcing Slysoft to continually create hacks around newer movies. Like someone said, earlier, BD+ was created with the assumption that it would eventually be cracked.

I guess, one could see this as a compromise for movie studios and consumers. I see it like this: A movie comes out with updated protection. Now Slysoft needs to work on a new hack for it. Well, that gives Blu-ray timed-exclusivity, the period in which the movie is likely to earn the majority of its sales. The hack comes later, when sales have already tapered-off. I see this as an "as good as it gets" scenario for movie studios, in a world where no copy protection can be assumed to be uncrackable.

I love these guys... I bought all of Slysoft's products because I love their company and their products and want to support them.

I don't find many products worth buying, in fact I could probably count the ones Ive bought on one hand over the last 20 years. Slysoft software is worth 10x what I paid for it, mainly ANYDVD.

Their software is incredibly good. It is updated with a regularity that amazes me. And they give you free updates for life.

As far as moving target goes, even with DVD's this is true. They are constantly releasing new ANYDVD updates to deal with the latest feeble attempt at keeping people from copying DVD's.

ALL HAIL THE MIGHTY SLYSOFT :)

AnyDVD and / or DVDFab might be all anyone with a passion for sharing needs.

DVDFab has been nothing short of amazing for me. Nothing has stumped it yet and is updated constantly for free. A Mac version is officially in the works too.

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.
