That gives me a couple of ideas to start with for reprogramming the remote.
1. When I enter the activity send a close command to the MC and then a start
2. Turn off the AVR then turn back on and choose the right input.
Because I know if I fiddle enough in the blind with the MC interface it will come back up. Now back in the day with my AMD 690G board I had to program a function to run HDMIon.
