Ive connected my Leadtek 6600GT to my TV through the the S Video cable. However, I cant seem to get a movie to display on the screen through PowerDVD or WIndows Media Player. I see everything else on the screen such as the desktop and the window the video should run in. But the actuall movie wont display inside window. And when I change to full screen mode, all I get is a black screen. Anyone have any ideas what this might be?
