Play back failed on bedroom tv - DirecTV

We have tried to watch from our list in our bedroom and it keeps saying playback failed no audio video data packets received from server. I have rebooted both boxes and unplugged both boxes and still won't let us watch from our list. The main TV and our other bedroom we are still able to watch from our list .

This question, "Play back failed on bedroom tv," is about DirecTV channels, programming, equipment, and sports.
