S-Video not working

WinXP Pro SP2, Geforce FX5700 256mb w/ latest drivers from NVidia. I went into the NVidia control panel and set it up for dual display first: listing my CRT first and the TV second. I made sure the SVideo cable was connected and that the SVid switch on the TV was on. No picture on the TV came up but the CRT stayed the same. So I then tried to go w/ a single display (TV only) and that didn't work either. Both the AGP card and the TV have the 4pin SVid connector.... how do I get this to work? My CRT is a bit dark and watching movies on it can be frustrating so I want to use the TV for movies.....
H E L P ! ! ! ! Thanx!

You don't say what kind of PC you have, but on my Lenovo laptop I had to configure the computer itself to output S-Video. It's not a "Windows" thing! Best start by looking at your PC's setup instructions - hopefully they'll tell you!
