Would it be worth getting an HDTV, or even a widescreen one for that matter? I don't currently have any dish feeds, and watch cable TV the majority of the time. Maybe 20-30% of the time I'll watch DVD's (the player has progressive out capability however, as well as component (RGB) out). I thought I read somewhere on here that if you watch cable TV too much on a widescreen there is burn in from the gray bars on the sides. Just have regular cable TV right now...would digital cable make any difference?
