I've tried to find this explained better in other posts, but couldn't find it. From what I understand, the 522 takes two feeds from the satellite. The first TV is hooked up directly to the 522. But this is where I am get confused. Getting the answers to these questions will really help me narrow down which rooms the 522 is going into. Does the second TV also get hooked up to the 522 through a splitter, or is it hooked into existing coaxial cable in your home? What if you have cable internet and cable television already running on those lines? Does it override those signals with satellite, or do you have to turn to a specific channel on the television to get the satellite signal? Does that mean anywhere you have a coaxial jack in the house, you can receive the second signal? How far does the second remote work? Does it work behind walls and closed doors? Between a couple of flights of open stairs? Does the 522 conflict with 7100/7200s in anyway? Do they try to get the guide from the satellite at the same time? Would appreciate any and all help!
