Hi,
I have an issue with Plex, that keeps wanting to randomly transcode a tv show when watching. Sometimes I can start without transcoding, sometimes it starts playing transcoded, sometimes when I seek position it starts to transcode while it was not before.
There’s subtitles, so I guess it might be related, but they are shown just fine without transcoding …
While this issue might not appear important, the main concern is that the burned subtitles are very ugly (really, is it possible to add some fonts and/or customize the burned subs?), and it’s wasting CPU time for nothing.

(I tried to remove personal data in theses)
From what I understand by reading quickly, it’s the client that asks for subtitles to be burned (but … why?). The burned subtitles settings is set on “auto”.
I hope there’s a solution, in the meantime, I forced video transcoding to disabled, but I don’t want to keep it disabled.
Best,
