I want to program my comcast remote to change the volume and turn off my denon avr 591 receiver? I need the denon code to program the comcast remote????

SOURCE: Need a code for my Comcast Universal Remote

30176 is the code you need . Press Aux and then hold setup until Aux lights up. Enter code. If you want the remote to control the receiver all the time, press Aux and then hold setup until Aux lights up. Enter 993 then press Aux. Aux will flash, now press Cbl and Aux should light up when you use the volume.

SOURCE: What remote control code does the Onkyo TX-SR304 use?

From: http://www.comcast.com/remotes/universal.html - only worked for me when I had AUX setup with 30135

Unlocking Volume Control For A Single Device (Individual Volume Unlock):

1. Press a desired mode key where you want volume to be unlocked (e.g., AUX) and controlled within its own mode.
2. Press and hold SETUP until the selected mode key blinks twice, then release SETUP.
3. Enter 9- 9- 3 and then press VOL- once. The mode key will blink four times confirming unlock.
   If desired, repeat steps I to 3 (of this section) for each device that you want volume to be unlocked.

Now, after you select a device that has volume unlocked (e.g., AUX), pressing VOL , VOL-, or MUTE will control the device's volume only in its own mode.
