There are no CFLs in the rig as far as I know. All are LED types. The remote works just fine with the Blu Ray disc player/sound system. When I press a button on the Dish remote, the receiver LED flashes, but the Dish box switches only maybe every 10 pushes. It works the same on the TV up front and the one in the bedroom. That eliminates any occasional bleed through via the cabinet louvers. The repeater box has 2 or 3 uncovered LEDs, which I assume emit an IR signal, but the receiver is at 90 degrees to it. So maybe it receives from that only intermittently. Guess I need to turn the Dish box 90 degrees to see it that works. The emitter buttons are attached via a plug and cable to the repeater box.
