Apple TV 4k streaming video keeps starting and stopping
I've been having an issue lately where I start playing a video from a streaming service that will go for about 2 or 3 seconds and then the screen goes black. Nothing happens and then it will sometimes flash back on and then stop again. It doesn't appear to be paused because the screen doesn't show anything, but pressing play again will sometimes start it playing again. I have to keep pushing play over and over. Sometimes it works and other times I need to go back to the main ATV menu, and then try to start the video over again. Sometimes I have to restart the ATV to get it to work.
It seems like it was originally only happening with Amazon Prime, and I think that's still the worst offender, but now it's also happening with Netflix, Apple TV+, Paramount+, Acorn, and Britbox. However, I don't think I've ever seen it happen with YouTube, PBS streaming, or Reuters. My ATV 4K is just a little over a year old, as is my Sony Bravia TV. I've also tried 3 or 4 different HDMI cables. This is really getting old, so I'll be very grateful for any advice.
