Having some wee problems here. I have the remote set up for my dish network system and all, with one exception, is glorious. The exception is volume control. The harware buttons do nothing in the Vol Up/ Vol Down and Mute Departments. In fact, the red LED barely flickers when I push them. ( I actually thought it did nothing at all but you can barely see the flicker in a completely carkened room). Although in manual mode, I can use the track wheel to run the command with no difficulty. How do I get the hardware buttons to do what they should?
