Plex Server cannot handle transcoding with subtitles

For 11.22.63, that file has SSA subtitles. There is an issue right now with that subtitle type.

1917 was transcoding due to the file having Dolby Vision. I’m not sure if the combination of dolby vision and subtitles is causing this.

John Wick, the app is indicating audio underrun, which means it’s not getting enough audio info in time. I cant tell why. I see that the file has 2 audio tracks. It’s possible the files were created incorrectly. Can you try remuxing the file with only the 1 audio track you want and see if that plays any better? If not, I’ll need the PMS logs during this playback to see if it logged any issues.
