Question from a new member........Have a 311 receiver we use in our RV. Used to have hooked up to a analog TV with a great picture. Recently bought a Sanyo DP26648 HD TV for use with both our rooftop air antenna and satellite. On rooftop air antenna we get a great HD picture. I know we can't get a HD signal with the 311 receiver, but get a lousy, grainy, ghosted picture on all channels when operating off satellite. Signal comes into RV from Dish 500 via RG-6 cable and is routed through a winegard distribution box. Air antenna is connected to digital jack on TV and 311 receiver is hooked directly to TV via s-video cable. Have double checked everything and am beginning to wonder if this new TV being HD doesn't like a straight digital signal. Any ideas? Thanks!
