I'm looking to save the fees on the extra 2 receivers I have (3 total, 1 DVR). Is there an easy way to set things up so that every room is running off a single receiver? I've got a HR24-500 and two H23-600s. I can't remember exactly how its hooked up in the back room at the moment. Just curious, as I only need to use 1 room at a time.
