My wife and I were enjoying the evening, watching a recording on our DirecTV in our 2014 Phaeton last Sunday when all of a sudden it began switching channels and deleting our recordings. I thought we were hacked by the Russians! I spent two hours with DirecTV and they sent a new Genie DVR but when I changed it out, same problem. We were battling with someone over control of our TV every evening.
We finally discovered that it was the neighbors next door in a Tiffin Allegro. It seems that their Infra Red extenders (receivers) are on the same frequency as our IR transmitter in the electronics cabinet. Even though our Genie DVR was on Radio Frequency Remote control it still picks up IR signals. Fixed it with Duck Tape over the IR emitters.
I hope this helps someone else with this very rare problem.
