I have 4 directv SD receivers that only have IR capability. I currently have 4 TV's mounted on brackets from the ceiling above my treadmills in my gym. I am adding LCD TV's to the treads and need a way to control the Directv receivers without mounting the receivers on to the treadmill. I know I can buy $99 HD receivers and a $10 (ebay) RF remote but that is $440. I envision something like an ir extension cable on the LCD running down and assumably into some repeater then stuck on to the front of the IR on the receiver. I also considered buying some old Directv receivers with the 3.5mm RF remote input on them but don't want a receiver that may die soon. It is my understanding that there aren't any new receivers out there that have RF except some DVR's and HD receivers. Will the RF remotes interfere with each other since I have 4?
Thanks,
Randy
