I'm using the Denon receiver setup code of 0160. It works for on/off, volume, etc. What I'm trying to set up is the advanced codes for the discrete inputs, and set them up on #'s 1 thru 5, so you can punch 3 while in the RECV mode and switch the input from the SAT feed to the DVD (I'm using the Denon as a true audio/video switcher, so I need to be able to switch inputs to get various feeds through the receiver to the TV). And yes, my dad has a Denon 5-disc CD changer, and none of the Denon setup codes will turn it on or off.
