I started getting this on my Windows 7 system after I added a 3rd video board. I have a gtx460 driving one monitor and a pair of gts250's in SLI driving a 2nd monitor. I used that Patch9 to upgrade to 9.0.4322.52. Googleing I see others with powerdvd12 and same problem.
I can play my blu-rays using the free DAPlayer but my paid for powerdvd 9 wont play any blu-rays anymore.
I disabled McAfee and also stopped BOINC (BOINC uses my gpu's for CUDA processing) and power dvd give the same error message
I tried both LG and LiteOn blu-ray devices and neither product works anymore except with DAPlayer.
[EDIT] - I brought up Nero's Blu-Ray player (Kiwi Media) and it worked fine after activating it's patent. PowerDVD 9 still does not work and still generates the above error. I also corrected the SLI devices name.
