I need to setup a small Xantech IR repeater system in my living room. My TV is a recently purchased Samsung plasma. I see there are "plasma safe" IR setups from Xantech but they are nearly 3x the price of the standard system. How far away does the standard receiver need to be from the TV to eliminate the interference issues? My TV is on a stand and I planned to mount the receiver at the bottom so it would be about 2-3 feet away from the TV.
