I would really like to put my XA2 in the closet behind the HT, but how do you do this and still control it since it is out of the room and the remote wont work through the wall? I am just totally unfamiliar with how this would work and if somebody could help me out with some info that would be great!

I had originally bought one of those pyramid style extenders and was not impressed. Did a little more research and found this little toy. 100 times better. First there is nothing sitting in the room, the transmitter is in the remote and most importantly it works every time. I had a little trouble with my Vizio remote but i'm not sure if that was my babies fault or not. Just upgraded to a Moxi box (in the closet behind the TV) and the extender has worked everytime from everyplace in the house. I highly recomend it. You can get it from amazon or buy.com
