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.

HDMI based HDCP stripper

Even if you can't crack the BD+ or other schemes, you can capture video at 1080i using a Black Magic Intensity Pro video capture card. It features component and HDMI capture.

To get around it not working with HDMI, I purchased one of the new HDCP strippers for HDMI. These are popping up from Asia, so keep an eye out if you want one. It basically makes the player believe it is connecting to a valid device and the stripper passes the data thru to the HDMI capture card. It is really quite nice.

I give it a year or two before so many of these HDCP strippers are making it into the USA that you'll be able to find them online without worry.

Something about the name HDCP strippers kinda turns me on.
