I have a dell desktop running XP with a Nvidea GeForce FX 5500 and I'm trying to connect my video card to my tv. My tv only has a coax input so I have to connect s-video to my computer. Then connect the s-video to an rf converter to connect to the coax on my tv. But the display on the tv SUCKS. When I try to play a video in windows media player, it plays fine on the computer monitor, but doesn't even play on the tv. Can anyone please help me with this issue? I would greatly appreciate it.
