I was going to chime in yesterday the same exact thouhts.

i.e. Really not sure why this is an issue. It more of an alert to the customer to say "Dumbass, you are using the wrong remote". Otherwise, if there was way to disable the msg, you will be getting the call from the customer or family member that the volume isn't working anymore on the TV.

If the customer doesn't want to spring for the additional cost of a custom programmed remote they have has two choices. One is to leave it exactly how you have it. message only pops up when watching built in content and as noted is a reminder that he should switch remotes. Other option is to program the Snap Amp to the Sony commands and get the message constantly, which then would be highly annoying.
