I am running WinDVD Version 4 through my Pentium 2 64 Meg RAM PC. At first it played fine but since I tried to play an SVCD film I have had problems. Now every DVD/SVCD plays with fine black horizontal bars all across the screen.

It only does this in full screen mode. If I try to play on anything apart from full screen the picture turns green and shows nothing at all, it just gives the sound. I have tried to play about with the options on the menu but to no avail. Any help or ideas welcome. Thanks.
