PowerDVD 11 Ultra was always unstable for me, but I could usually get it to show movies properly. The problem that I have sometimes had is that the blacks in the image (on Blu-Rays only) would sometimes be gray instead, making the whole image too light. Recently, PowerDVD went gray and won't go back to black. No matter what I've tried, it won't fix. I realized that my monitor cable was not fully HDCP compliant even though my Samsung monitor is labeled as HDCP compliant. So, I replaced it with a fully compiant cable expecting the problem to be fixed. To my shock and horror, the Blu-Ray movies are still gray. One problem that happened right before PowerDVD went gray was that I accidentally installed a demo for PowerDVD 12, thinking that it was a normal update (since PowerDVD told me that it was an update). After having the demo on and then removing it, my Blu-Rays have all been gray and I can't get it fixed. I tried re-installing many times and have tried the most stable graphics driver (for PowerDVD Blu-Rays). I even tried going into my registry and removing PowerDVD 12 entries, but it still hasn't fixed. Right now I am forced to use DVDFab to watch Blu-Rays, but it's just a demo. If I can't fix this, then I will simply use another company's software and never go back to CyberLink again. This has been a nightmare. Thanks for giving me trash software that has wasted a lot of my time. Now, does anyone have some answers? Please.
