I have 4 directv SD receivers (D10s) 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 treadmills. Ideally having the ability to point the remote toward the LCD and it work. I know I can buy 4 $100 HD receivers and 4 $10 (ebay) RF remotes but that is $440. I envision something like an ir extension cable on the LCD running down and I assume into some repeater then stuck on to the front of the IR window 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

Right, only SD & HD dvrs, and Hd receivers have RF remote capabilty.

The problem with your D10's are they only know 2 IR codesets, there is no way to control 4 D10 independently. Unless you go with RF addressable universal remote like the combination mx350 and separately sold RF basestation like the mrf260.
