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.

They could cut prices and sell a lot more dvd's, but their strategy is to maximize their profit and screw anyone in their way (even legitimate buyers)

You see it all the time, people on the streets hawking low quality $5 knock offs. If media companies were selling DVD's for $5 each I doubt you'd see as much piracy as you do today. And they wouldn't need copy protection and they wouldn't screw Joe average DVD owner in the process, and they wouldn't piss everyone off with DRM.

Honestly how much does it cost to produce a DVD? 10 cents? At $20 a DVD that's a lot of money. They're probably seeing the situation in green colored glasses.

Media companies have the right to protect their intellectual property from abuse, but if they played the market right, they wouldn't need to use DRM and cry about illegal copying etc.
