You could create a test library and add a few problematic files to it, and then share the server logs here.

My next suggestion - after a remux test - would be to Plex Dance a few ‘misbehavers’ to see what that does. It also wouldn’t take much for me to believe Plex has a few locked up in some kind of hellish limbo a Plex Dance would cure…:

The Plex Dance ™

The purpose of this is to remove all cached metadata and xml data for an item that Plex usually keeps. This helps when you want to “start from scratch” for particular item move all files for the media item out of the directory your Library is looking at, so Plex will not “see” it anymore scan the library library (to detect changes) empty trash clean bundles (in menu next to server name, when accessed under ‘More’) double check naming schema and move files back scan the library Support articl…

Making a test library would do the same thing - either/or to find out what happens.

@Volts

I still have some of those problem files. Plex can extract VPTs from the ones I have.

I think I have all those fixed - then I find another one.
I can’t recall what happened during the VPT gen phase - I had my head down for a few weeks on ‘The Fix’ - or in my case - ‘The Re-Acquire Then Fix’. It was a dark time.
