Hi, I would like to use my Amazon Fire TV, Flirc & MX-850/MRF-350. Ideally I would like to have 3 TV's share the amazon box (same content in all rooms) but cant figure out how to manage three different TV's (Sony, Sharp, Samsung). I was thinking I can program the TV's using the MX-850 but am a little confused on Flirc/Amazon TV. I have my current MX-850's programmed for my cable tv boxes which I want to dump. Thanks, Rich
