I have a Sony DVD and a Nintendo Wii that are connected to the Tv's Component 1 and Component 2 inputs. I need a way to tell the MX-450 remote to change the tv source from whatever it is currently set at to either Component 1 or Component 2. I'd like to make a macro to start the DVD, but I can't choose which source input for the tv. The closest I can get is to send a Source command to the tv which brings up the on-screen source menu. Is there another way to program the tv source inputs into the MX-450 remote?
