I had that problem with my powerDVD as well. And, I was running it on a very high end system, so I know it wasn't on my end. I would update drivers, etc, and never could fix it. I saw many other happy users of PowerDVD, but I eventually gave up and bought TheaterTek. Haven't had that problem since.
I know its not a fix for your problem, but I posted something similar awhile ago and someone said just buy Theatertek, so I did and never looked back.
