Go to Menu, Settings, Parental Controls or you may see Remote Control.RF Setup. Program your tv first. Test the volume. If it worked. Select - It worked. Next - another screen should open up and say Program Audio Device. Select it. A search box will open - Type Denon. After it is found - Type your model number of your Denon receiver. It will check to see if it finds it. Select - Volume lock. It will do the volume check. Point Denon remote at the tv. If the volume worked. Select - It worked. Then select use audio device. The remote should work for it. I am assuming the DirecTV remote will control the volume for your Denon receiver. Lastly, these instructions were for my HS-17 server. Your DirecTV receiver remote control setup could be different depending on your model. Hope this help's. Let us know if this worked for you.
