I have noticed that watching regular low-definition TV channels on a HDTV looks better if I use the s-video connection than either the DVI or component inputs. More specifically, the picture looks blockier (more quantized) than the s-video, which is more smoothed out . This is really annoying since it means that I need to switch back and forth all the time.
Does anyone know a way to make the picture look better on regular stations when running on the DVI connection? I don't know if the problem is in the cable box when it up-converts the signal. It may be that it's simply stretching the existing pixels, thus creating sharp boundaries and the blocky look.
