I have just installed Windows 7, everything is working great with the exception of PowerDVD. On my old XP system i ran PowerDVD 7 and it work perfectly for Blu ray playback. However, since running Win7 i have been unable to play a single Blu ray disc. I original thought the software needed to be upgrade due to incompatibility, therefore i upgraded to PowerDVD 9. However, this has not solved the issue. PowerDVD loads the disc and i hear sounds,but no pictures. i can see part of the menu screen, no background just the menu button graphics, which can be clicked on. If i proceed and load the movie, i still get sound but no pictures, just a blank screen. Has anyone hear or suffered this? Any help wold be appreciated. p.s Blu ray playback works on another programme WinDVD 10. but is unwatched. my computer cant seem to handle this programme. BUT i have played Blu rays on this PC before, so i know it works
