My friend has a Leadtech Geforce2 64Meg card and they want to try the S-Video output on their television so that they can watch DVD's on their TV. I saw in the drivers where you change it from monitor to the television output but the TV output is grayed out and will not let me select it. Is this because there is not a TV connected to that output yet? Does it know when a television is connected? Also what kind of video quality can they expect displaying dvd's on their television using this output?
