I am in the process of setting up my Home Theater System. It is going to be a pretty basic system. 1 Receiver, 1 Digital HD Cable Box, 1 DVD Player and the Plasma TV. My equipment is going to be located on a different level from the TV. I want a single remote that will control all of the equipment and to be able to control the equipment from a different level from the TV. What is the best way to set this up? I am guessing a universal remote and a way to extend the signals? How do you suggest hooking this up all together?
