chris....i've done some thinking about the same issue. i'm actually planning on doing the same thing only my tv is about 50ft plus away. i know that will be pushing it, but it's worth a shot. one site i found has a 50 ft s-video with R/L RCA cables for a reasonable price. haven't ordered from them and have no idea about the company, but here's the link. hope it helps.
the 25 ft. cable is ~$27 + shipping..........if u need a little more length they have the 50 ft. for $40.
