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.

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.

Oh really, thou who knows all?

People have already used this to re-encode formally BD+ protected movies into different formats, and have burned the unprotected output to BD-R discs and played them in set-top players and the PS3. BD players will play discs with no content protection, which is exactly what you get after using the new version of AnyDVD HD.

Yes, please show a picture of yourself ripping a BD+ movie. Be sure to include your name and social security number as well (for verification purposes)

I don't want to spend time hunting down public posts, but it's very much real. I'm on a private backup site (i'd link you but it's private) where the users were posting about trying the new AnyDVD with known BD+ movies (ice age, simpsons, live free, I Robot...). it's been agreed upon that it works for most movies. this is not a "huh look at me i did it first" site, this is real discussion. i've seen before and after screenshots of BD+ playback before and after AnyDVD. with BD+, the playback is garbled. they were testing the beta that was accidentally put up on wednesday, the final may work with all BD+ movies. you're right to doubt, but i can tell you that it works, at least for most current movies. i'm sure they'll try to change the BD+ on new discs to stop AnyDVD.

Do you even know what AnyDVD is? The point of AnyDVD is to remove the DRM from the discs so that you may use it as you please. He doesn't need proof because Slysoft said it works. I would tend to believe them based on the history of their products.

Quoted from AnyDVD HD changelog
New (Blu-ray): Removes the BD+ protection from Blu-ray discs!
(for increased compatibility with titles released by Twentieth
Century Fox :-) )

It looks like it says removes BD+ to me.

It's already widespread on privte torrent tracker sites, people have ripped and encoded via x264 movies like the new Die Hard, Ice Age etc.

Why does the hardware have to with circumventing BD+? If all traces of DRM are removed from the disc during the ripping process as AnyDVD does, the player thinks it is just a regular unencrypted disc.
