SRT files are often not displayed in Plex

This has been translated using translation software.

I’d like to talk about SRT files for a moment.

I frequently encounter situations where an external SRT file is present alongside a movie or TV episode, yet Plex fails to recognize or display it.

Often, I have to delete the SRT file, add it back, and trigger a library scan multiple times—and sometimes that works. But usually, it doesn’t.

I’ve started replacing the SRT files for all my movies and series with ones I know are valid, copying the text over manually. Even then, Plex often fails to show the subtitles or throws a playback error, even though there is nothing wrong with the SRT file itself. Plex is the only system that has trouble with this.

And with a series, it might detect some episodes but not others, or none at all—it varies. Sometimes you’re busy cleaning things up, analyzing, and so on, and it still doesn’t pick them up; then, a little later, it detects a few but not all of them.

Where is it going wrong? I’m getting really fed up with this; it ruins the viewing experience and the convenience Plex is supposed to offer when I have to go to my computer and fiddle around for ages while everyone else is left waiting.
