Hi
I recieved the above message when trying to play Iron Man and the Hulk. None of my other Blue Ray Discs(brd) would play. I had updated my graphics driver to 178.24 Nvidia.
A complete reinstall did not solve the problem after many hours of retrying and web research I came across this post
http://forums.nvidia.com/lofiversion/index.php?t35009.html (please follow the link). So the problem is done to pirate protection in the form of HDCP. I solved the problem by update of the graphics driver with 163.75 from Nvidia my machine is a VGXL 302 media centre. I only have an LCD TV connected to the computer.
I now have full 1080p not 1080i and am able to watch all brd.
