@SoNic67, thank you, I see that does answer my question as I typed it. But apparently I didn't provide enough detail. What think I need is something that can go from an IR box like this...
This receiver has an "IR IN port"

Please correct me if wrong, this port is so you can setup an IR receiver elsewhere, and have it forward infrared remote control signals to the A/V receiver, correct?
All...
