I'm going to be picking up a new 27" CRT with 4:3 aspect ratio (used primarily for older gaming consoles) and want to get the best possible Dish Network picture while maintaining the correct aspect ratio. The TV has component, composite and S-video inputs. Would I be better off using the S-video output from a Dish Network receiver (either a 211k or 311) or could I output component at 4:3?
