i recently got cable with the hd receiver and don't know if I have the set up correctly. I do know that my tv has a QAM device built in. Currently, I have it set up through the s-video connection instead through the RF, which I heard was of lower quality. I have tried to see if some channels looked "HD" but I can't tell because I don't know if I have it set up correctly. I don't know if it should be connected through RF or S-video. Thanks for the help.
