Here's the lowdown. Satellites Unlimited comes out tomorrow to hook up our Dish (after much hassle with them). The guy said he is hooking up two recievers for our four rooms. My question is, will this interfere with the quality of the picture? Also, will each room have their own set of channels rather than having to share the receiver with another room? Thanks in advanced. If it helps any, we are having the 180 (plus a few movie channels).
