Watching HD issues - DirecTV

So I've always been able to use 3 HD streams. Today this issue started-recording 2 HD, watching 1 issue. Unless I want to change the channel. All other set top boxes are off, but I am being forced to watch only THIS live channel in HD or it says I have too many HD streams running. It makes zero sense. Any clue why this popped up today?

This question, "Watching HD issues," is about DirecTV channels, programming, equipment, and sports.
