No, I believe it is your TV, plasmas are known to have issues with streaming, they have to process the signal from your Apple TV also.
First, go into your video settings, I assume you have it set at 1080P since it is not a 4K TV, change it to 720P to see if that makes a difference.
And when I said none, that was to say no issues at all streaming on any service.
Have a 8K Sony Z9K, a Sony A90J OLED and a Optoma Projector outside, no issues streaming at all on any service.
But if you are going to switch back to Satellite, now is the best time since they are doing a two year price discount, still more then YTTV with the fees, but better.
