I just had Dish installed on Wednesday of this week. So far, I am really enjoying it. My question is the 722 DVR. My old D* DVR (R22) had an s-video out as well as HDMI and component. I used this to hook up to my receiver for subsequent recording on my DVD recorder. The 722 does not have an s-video output now. I had the install tech hook the rca video output - but I do not seem to be getting a video signal. I have audio, but no video. Any ideas?
