Ahh the Digital Age - Nothing Works!!!? ?(In other words, if something doesn't work 100% of the time, it's broken...)
j5aces - I tried your method with the Generic Source Module, and it did work well (Nice to have discrete Play, Pause!)...
BUT, the 'Media Top Menu' command still pulled up the TV App, no matter what the settings...? Could be something weird with my box, but for me that's always a lame excuse by manufacturers and programmers...:)
In a related story, I changed to IR and the 'MENU' press creates the Back command, while a P+H on the 'MENU' Command does return to the Home Menu.
In fact, no matter how I set the Settings > Remotes and Devices, P+H always calls the Home menu, which is kind of what I want anyway...
