How to use 2 IR receivers ?

Riva:
Where I work we had a Satellite box at one end of the building and someone who wanted to channel change it one floor down and at opposite side of building. We de-soldered the IR LED from the remote and placed it on about 50 meters of screened audio cable at the satellite box and it worked a charm. I would assume IR receiver would work just as well.

That's even better. Thanks for sharing. If my logical gate does the trick, I'll solve my problem!
