I plan to follow JLET's suggestions. One trouble I foresee is that the Mitsubishi remote does not have a "Input Next" button, but the Logitech webpage software asks me to press it. When I skip that step, it asks me to press the "Select" button, but the Mitsubishi remote does not have that button either; instead, it has "Enter," which I assume is the same thing. Also, in device "Adjust Input," I don't see the heading "LABELS" anywhere; instead, I see only "Input Names," which I assume is the same thing. Finally, I have never seen a drop-down list for the correct command(s); instead, I only get one list, for "Input Names." As an aside, I believe that the Logitech webpage and software were written by people who know what they are doing, for people who know what they are doing. Obviously, I don't know what I am doing.
