Anyone knows of a simple/cheap device to extend infrared? I have a Comcast STB about 75 feet from the TV fed using 5x RG59 cables and that works great. Now I would like to be able to change channels while in front of the TV. Any suggestions. Ideally it would use cat5 cable and cost under $50. I looked on eBay and see a few devices that use 3.5mm cables. I don't need multiple anything just 1 IR in and 1 IR out.
