Try deleting your prime time preferences and turn it off , then pull the plug , then plug it back in and then go back in and redo the Prime time anytime preference and turn it back on . See if that helps.
As an example AGT is two hours, so there is two events that night and that has happened twice a week a couple of times. Same with American Ninja Warrior on Monday. So there's three days with two prime time programs. And I think The Night Shift is two hours coming up. All NBC.
Oh Great!!! I am a big fan of the Olympic Games. That is the reason why I put NBC on Prime Time Anytime, so it would be a guarantee of recording it on the Hopper 3. I will let you know, but I am thinking that last night, America's Got Talent recorded. I think we have had only a few incidents, and it was not on NBC, but ABC.
