delirii:
Just to contribute to the knowledge base: I've tested with some 5 meters long cables, clearly not the best quality cables, and my (single for the moment) receiver works like a charm.
=> That's a good point!
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.
