More info please
I can help you out, but you also have to step up and take the time to write down all the info and post it here. That way we know all your options. Makes/models. and how precisely everything is connected. Something like the following makes it really easy for me to troubleshoot-
Skybox (HDMI out) --> (HDMI in) Denon
Denon (HDMI out) --> (HDMI in) HDTV
etc., for all components in your system.
