I recently purchased an H20 receiver. I have it hooked up by an HDMI cable to my Samsung slimfit 30" tv. My problem is that I can only view the HD channels or my digital OTA channels via HDMI. When I try to watch any other channel on D* is on I receive a blank screen no audio or video. My question is has anyone else experienced this problem and if so what do I need to do to fix the problem? I hate having to keep switching to component input to watch the other channels and HDMI is by far a better picture on my tv. Thanks in advance for any and all help.
