My HT in progress/planning has some of the IR receptors (for the remotes) of the equipment disappearing behind the doors of our armoire style entertainment cabinet. I would consider replacing the furniture, but we really like the piece. Now, it's only my new DVD player-but soon my new receiver will be hiding behind a door. It's awkward to leave the bottom doors open when in use. I have heard of devices that can solve this problem, but how well and where can I find out all I nee to know? Thanks in advance.
