My current TV is set to S-Video and I cannot get it out of it. So as a result, any composite picture will come out nearly black and white. If anyone has an S-Video cable for the Dreamcast they can give me, or that I can buy. That'd be great.

It's funny though. When I got mine, it was about $3, Free Shipping. They must be running out of stock. P.S. Your problem is opposite to mine. When I plug in S-Video, it goes black and white.
