Want to put comcast/xfinity box XiD-C in a cabinet and control a 20 inch kitchen LG TV . The box is small with only 4 ways to connect; a power source (AC adapter ), ethernet, cable in, cable out. Have a channel in wall to hide ethernet and cable. What ir repeater works with this? All the ones I see to buy stick on to the TV and "plug in" to the box. But there is no way to plug in. The power adapter is a propriatory green connector, EPS-2.
