I recently installed a gc-100-12, denon 2313, comcast (cisco) cable box, vizio tv and apple tv. Everything is working fine except the IR control of the cisco box. Only when I hit the channel up or down button the ir freaks out and sends multiple commands to change the channel. I have tried all 3 versions of the IR code set provided by Roomie, but none of them seem to remedy the problem. Is there a way to slow down the ir pulse or make the control more reliable?
