We currently have 4 tv's (1 in the living room, 1 in the bedroom, 1 in the kitchen and 1 in my hobby room/office) with DTV in the living room and bedroom. I attached an RF Link transmitter to the tv/dvr in the bedroom so I can watch tv in the kitchen or hobby room. I'm now wanting to reconfigure the arrangement. I want to "link" the living room dvr to the bedroom tv with a RF transmitter/receiver. I want to move the bedroom dvr to the hobby room/office and "link" that one to the kitchen tv with a RF transmitter/receiver. What I would wind up with is the living room/bedroom tv's "linked" then the office/kitchen tv's "linked" both via 2 RF transmitter/receiver systems. My question is - if I use 2 different brands of rf transmitter/receiver, will they work and not interfere with each other. Currently I have an RF Link 5.8 GHz transmitter and receiver. If I purchase a different brand (maybe Terk or Nyrius or IOGear or...), will they work independently of each other? I really don't want to pull wire through a 2-story house!
