Remote will not operate main receiver - DirecTV

I have a recently installed system that uses wireless receivers for other TV's. The remote for the main receiver will only turn the TV and receiver on and off, and control volume. It won't change channels, or access any other feature. All other TV's using the wireless receivers work properly. I changed the batteries in the remote for the main receiver, reset the receiver using the red button on it, and also unplugged everything for 30 seconds. Nothing has worked. I also noticed the "record" light is on, but I have nothing recording. This light comes on after each time I have reset the receiver.

This question, "Remote will not operate main receiver," is about DirecTV channels, programming, equipment, and sports.
