when I buy a iTunes movie and convert it with M4VGear (Windows) the Playback on iOS, tvOS and the Webplayer is stuttering.
On tvOS it where it runs best. Every 3 to 10 Minutes is a very small interrupt (around 0.5 to 1 sec). On iOS and the Webplayer is much more frequent.
If I copy the same movie to iTunes and play it on the AppleTV with the "Computer" app it's absolutely stutter free.
If I convert the movie with M4VGear (MacOS) it's also with Plex stutter free. But converting a movie with MacOS M4VGear is a bad idea... because it takes hours instead of minutes like on Windows and even more worse: there is a visible quality loose in the picture quality (but the same file size).
All streams are direct plays
I think the issue is caused the Plex Server, after the issue appears only when I play the movie via Plex.
