I have a cable box that plays onto my tv and a computer in the office which broadcasts it's input onto 4 different lan computers (29 FPS.. Looks great full screen on all four computers). Now I wonder if I could extend the remote's signal receiver on the box into the office next door using some kind of extra antenna or something. Is this possible? Having two signal receivers would not damage the box? Would be nice for the ability to change the channel in the office as that's were it's broad casted to others here in this insane penny pinching household.
