I am a Dish technician and I am trying to program my surround sound receiver to the aux mode on my 21.0 remote. I've done the power scan by holding aux then hitting * then hitting the power button and channeling up to scan through but no luck. I've tried the few codes that they have for my receiver but no luck. I can get it to program in dvd mode but it does me no good because i can't change the volume on the receiver through dvd mode. I need a code to get this thing working through the aux mode. It is a philips HTS3440/37 reveiver.
