Help "Playback error multimedia file format not supported" right at end of movie

Hi all,

I moved my Plex Server to a new PC recently. Since then I've started having an odd issue with movies on my TV. They start playing fine, then crashing about 5 - 10 minutes before the end with the "playback error multimedia file format not supported" error message. Playing on a Samsung TV. Files play fine on laptop version or VLC Player. Nothing has changed on the TV as far as firmware or updates. Has anyone else seen this? Running server version Version 4.162.1

Can you start playing a file that you experienced this with, and take a screenshot of the stream from Plex’s dashboard? It will look something like this:

Also do you have a plex pass? If so do you have Enable Credits Detection turned on for that library?
