The HD-PVR's blaster does indeed light up when a signal is sent through it. Probably a supplementary nicety added to give visual feedback that the thing at least appears to be working. I suspect his emitter is fine, the real issue is finding exactly where to place the thing. As I've said in other HD-PVR threads, the emitter on these has a *really* short range. If its off by even a centimeter when blasting to an mce transceiver, the mce transceiver doesn't pick up the signal, and the mce transceivers have some of the best reception of any device I've played with. I repeat: its *VERY* finicky, you must have it precisely positioned over the target receiver, or it won't work.
