Hi I had Cyberlink PowerDVD 8 but was getting BSOD on trying to play a blu-ray in Windows 7 64-bit (error 0x0000007E file nvlddmkm.sys). Cyberlink gave me PowerDVD 9 and asked me to update the drivers for my GTX 480 graphics card.
With the latest v260.99 drivers PowerDVD 9 appears to play blu-ray (I tested for 40 seconds) but in games the screen is squashed so black bands appear on the left and right (I tested Left 4 Dead). If I restore the old v258.96 drivers the games work but I get the BSOD again on trying to play blu-ray.
I would be very grateful if anyone has some ideas how to fix this? I ran memtest but no errors, the PC is new (3 months old), and everything else seems to work (e.g. my ATAPI iHOS104 ATA Device blu-ray drive plays DVDs on PowerDVD fine).
