I just bought a corner unit for my office TV and it has shelves underneath. On the front of this is a door with quite a wide wood surround with glass in the middle. The problem is that my Sony Sky box has the remote 'eye' under the power switch on the far left and this is now behind the wood. Everything else works fine but to watch Sky I have to have the door open. Are there any small, cheap devices that will pick up the signal and repeat it inside the cabinet?
