My parents just bought a Sony 30" widescreen HDTV. I can tell the picture tube is good, but cable TV looks like total crap on it regardless of any widescreen stretching. Right now I'm using a cheap ass composite cable from the cable box because we don't own a s-video cable. Can I expect a significant improvement after buying a s-video cable tomorrow? The best way to describe what it looks like now is when you run Windows in 16 colors.
