Apple TV 4K 14.3 No longer plays music vids full screen
I have some music videos I've download over the years that I have on my MacBook Pro, and use the 'My Library' function on Apple Tv to play them on the big screen. I now have some very odd behavior happening....I start playing the 1st video, and it plays fullscreen. If I skip to the next video via the remote, it plays in a small box in the center of the screen. If I go backwards to play the 1st video (which was originally full screen), it is now also playing in a small box center screen. I think the only thing that has changed since last time I played videos (when they all were full screen) was the move to 14.3. Can you let me know how to solve?
