Just to make this clear, when you are addressing the remote to use the AUX mode to control a surround sound there are additional steps. You have to add a number before the equipment code and then set-up AUX Volume override so when you select the volume on the remote it works the amplifier and not the TV:
Programming AUX function on remote:
Press and hold down the AUX button on the top right side of the remote until all the other buttons on top light up and then let go.
If you are programming a code into AUX Mode, you must do the following before entering the device code:
Press 0 for a TV (if TV code is 500, enter 0500)
Press 1 for a VCR/DVD (if DVD code is 617, enter 1617)
Press 2 for any other device (if device code is 639, enter 2639)
Then enter the 3 digit device code found
here.
Press the Pound (#) button under the number 9.

Then you will need to place the remote in Aux Volume override which will have the remote change the volume on the surround sound and not the TV.
