I'm not sure if this is known or not, I do not see it listed in the known problems list. Attempting to play blu-rays in cinema mode, PowerDVD 11 would freeze early on, usually with a blank screen. In most cases, no event reports were formed, the program had to be ended, and the system had to be restarted before it could run a disc again (reporting that the video card was not appropriate on subsequent attempts without a restart). In one case, the program itself totally crashed and the system reported a serious error in one of the video driver processes.

I noticed something strange and believe I have discovered a user-fix for this although the problem may still be worth investigating from the company side. I had already found that the same blu-rays would play perfectly with the program in normal (not cinema) mode. However, I happened to also notice that cinema mode was forcing Aero effects to turn off while the normal mode was not. On a whim, I decided to change my display profile to a non-Aero theme and tested cinema mode that way. So far one blu-ray was able to play for probably 20 minutes and I'm testing one now that I know crashed before and it has been playing successfully for about 5 minutes now. The crash usually happened very early.

So to sum it up, it appears there is a conflict (at least on my system) related to PowerDVD 11 cinema mode attempting to disable Aero effects. This conflict apparently has the ability to crash the intel integrated video driver process in addition to the program itself.
