I know this is an old thread recently revived. A Google search for the software led me here.

I am not looking to add to this argument. I bought the remote at the same time I had Audio Advice (Charlotte) install a TV, TIVO, audio/video receiver, and Sonos in my new home three years ago. I have the invoices to show that I paid full retail for the MX-780 and am happy share them.

I recently added an Amazon Fire TV and want to add the ability to switch the receiver to auxiliary input. I am retired now, but had a long career in IT, so pretty sure I can figure out how to do that.

I can't get the software from Audio Advice. Any of the other dealers on here willing to give me the software? Please PM me. Thanks.
