Just installed my new Leadtek 6800, which is working pretty well. My only problem thus far has been the TV output. I've connected my TV via S-Video using the "clone display" option. My desktop and games display normally. However, I am unable to get video files to display (avi and mpeg). I have tried using WMP 10, Winamp 5, and BSplayer. All display the program's display controls, but no video. I assume this is some sort of copy protection, but it makes the feature pretty useless without the ability to play any kind of video on my TV. Is there any alternative? Is this a codec, video player, or TV-output issue?
