I’m having occasional stutters on some 4k movies on my sony tv.

I just noticed that I have some occasional stutters on some 4k movies. (Some run without any problems, I don’t know why…)
I also tried to play the same movies on the standard video app and it works without any problems, so it has something to do with Kodi.

Is anyone else having the same problems? Is there anything I can do to solve this?

I’m very grateful for any advices!
