I have a DirecTv genie proving input via hdmi to the AV Recvr. With the AV on, sound and video flows thru to the tv. If I turn the AV off, the pass through works and I still get DTV on the tv for as long as I have DTV on and watching. If I now turn off DTV and turn it back on 10 minutes later. Pass thru does not work. I have to cycle the AV on and off again. Any ideas to keep the pass thru open?
