I just bought a new 39" Emerson HD TV and I am having a terrible time hooking everything up. I have a combo VCR/DVD player and a Bell Satellite HD PVR. When I disconnected my very old TV, I hooked everything back up the same and now I can't get my combo player to work. I originally couldn't get even my Satellite to work but I finally figured out that I need the HD cables, as well as the red/white/yellow cables plugged in.
