I've got an Mitsubishi WS55613 TV that I'm trying to setup in my MX-850 and I'm having a difficult time finding a discrete command for my antenna input (ANT-DTV). It appears that it is mapped to DTV-2, but it not working correctly. When I on the antenna and hit the DTV-2 button it stays on antenna. However if I select COMP-1 (DVD) the input device switches correctly, but when I select DTV-2 to go back to ANT-DTV I lose the sound. The only way I can get the sound back is to select the ANT-DTV device.

Is there a way I can learn a code to do this? Basically there are only two inputs I will be using: ANT-DTV and DVD. I think once I get these codes I should be able to program the macro to set everything.

Thanks!
