[Bug] Stuttering Playblack with movies encoded with M4VGear

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.


Plex Server (@Synology DS415play)
Apple TV 4k with tvOS 11.0 (Plex App 1.17.1 )

iMac 5k with macOS 11.13
Windows 7 via Parallels Desktop running M4VGear 5.3.4

    Okay... I think I found a solution.
    I tried Emby and found the same stuttering as in Plex.

    After that I remuxed the suttering movies with ffmpeg and after that the stuttering was gone.
    I used for remuxing the mp4tool (http://www.emmgunn.com/mp4tools-home/).

    But it's still strange that the stuttering did not appear in the Computer app on the AppleTV or QuickTime/VLC on MacOs...
    I'm still not sure if the error comes from the windows version of m4vgear or Plex/Emby...
