I just purchased a URC 6131 and own a 65 inch Mitsubishi tv model ws-65877. The original remote had a very useful key labled " Home Theatre" which would automaticly match up the correct audio input with whatever video input was currently being displayed on the tv with the single press of this button. Does anyone have the 3 digit code to program this feature into my urc 6131 or is this not even possible?
