Presume you have both digital and analog cable. Feeding your cable directly into a set and running a channel scan registers only the analog channels. If you're getting suspect pictures now with either, problems will be magnified by larger or line-doubled images. Cable quality is very dependent on local companies, how extensively they're using hybrid fiber/coax hardware to reduce noise and other interference, and how much compression they use for digital channels. I've been on an analog cable system for a few decades and a digital/analog setup for about one year. Images from both, even blown up to 7 ft. starting in 1972 and fed into a 64-in. HDTV starting last year, have always been excellent. -- John
