I just came back to Directv after a couple of years. I have a whole home setup with a HR54-500, 1 4K mini, and 2 HD minis. I have noticed on some channels the audio and video will freeze for about half a second sometimes. I have noticed it more on the movie channels but that might be because we have been watching them more at night since there is no sports on. I would say it happens on average 1-2 times per hour. Is this something everyone sees or could it have something to do with my setup?
