Error when watching recording, live audio pixel probs

I consistently deal with recording viewing being interrupted by an error message, or a server message. I have missed the end of sports games, movies and the oscars. I can turn off the tv and come back later and start the program over, but when it gets to the same spot the recording will stop abruptly with an error message showing,

I also get dropped audio and pixelated and frozen pictures. Picture can be frozen as audio plays or picture will play while audio is silent. Then there’s the times I deal with pixelation.
