I have a Denon myself. Like the other poster said, the DTV remote can only control the volume on the AVR. The power on/off does my TV and DVR only. I have to use my AVR remote to power that on/off. HOWEVER... I *believe* if you get a CEC compatible AVR and have a CEC compatible TV, you might be able to have the TV turn off the AVR through the CEC connection. Then you can do it all through the DirecTV remote.
