stuttering sometimes on Fire TV stick

[Lance]

Ok, it sounds a bit similar, especially since its only some movies and server performance is most likely not the cause. Although in my case the playback is not slowed. After the stutter it just "jumps" to the current position and "resumes" play (well, for like a second or less, before its a freezeframe instead). Interesting to see that chromecast is also affected, but playback in the webbrowser not. Maybe the problems comes from jellyfin for android?
