When I try to play a standard DVD in PowerDVD 8 Ultra the video flickers. There is no flickering with Blu-ray discs, and PDVD is the only player that has his problem. Windows Media Player / Media Center, VLC play DVD fine. I've tried changing every setting I can think of and even did a clean reinstall of PDVD to no avail. Anyone have a solution to get this problem resolved?
