I have a GeForce 4, 420. I run windows me and have dual outs (one for monitor, one for s-video that I run to my tv). When I install the new detonator driver pack, everything works fine but my tv out. The desktop shows up on the tv, but if I have mediaplayer playing something like a cartoon lets say, the picture doesn't show up. The mouse and everything moves around on it, but no movie. Anyone that knows whats wrong please gimme a hand.
