I checked the logs but I don’t see any obvious issue 
Do you have “Match Content Frame Rate” enabled in the tvOS settings?
Also in the app settings you can enable Show Enhanced Video Player Debug Overlay, it will show an overlay with tech info on top of the video player, with some relevant data like the number of dropped frames.
Could you enable that and keep an eye to the number of dropped frames? In theory, when the problem you describe occurs, that number should be increased.
Could you take a photo of the screen when that happens and share it with me? (Important: cut out the first line in the overlay with the file URL from your photo, since it contains the token to access your server)
Thank you!
