Mysterious. I seem to recall something about Plex analyzing the files during maintenance. I wonder if, during that process, it sets up a parameter that tells the server to transcode that file or not.
Edit: found a link to a relevant post…
I haven’t tried Plex for Kodi yet but it sounds like I need to set that up as a fallback/troubleshooting player.
Looks like we are all getting slightly different results for the same files on the same hardware. Odd.
Edit 2: I found this support page that discusses this topic (but it focuses mostly on remote play).
