Here is what I am wondering. I am looking at a few very cheap video cards to use for testing right now. My main use will be for DVI testing, however, these cards also come with composite or S-video. If I get a card with composite output, IF I use it, the rca video putput will work with more TV's. If I got the S-video output, it should look better, but if I want to connect to an older TV without S-video, I would need an "adapter". Do S-video to composite adapters actually work?
