Dick,
Good luck on your quest.
I have a Logitech Harmony Remote at home and it runs everything well using a Denon Receiver, Dish Sat Receiver, and a Samsung TV among other things. It may take some debugging of a program with Logitech but once it works, they run flawlessly at least for my units. Once in awhile some component will miss a code if I was aiming carelessly, you just hit help and it goes through a question and answer routine and it fixes the issue with you. Very good solution in my opinion if the RF to IR interface works well.
