I’ve got a 3TB external drive that has files dating back to ~2001, and it’s chock-full of DVDrips from my library. It was initially formatted for an AppleTV/iTunes movie/show library, but now that I no longer use Apple products, I’m trying to migrate to Jellyfin. an example would be like the file I included, as it has the “bonus” stuff.
VLC is able to detect and play it, however as this is intended to be watched remotely, I would love to be able to have it detect the extras, chapters, and etc as all one file. I have ~300 movies like this, so deleting+reacquiring would be a massive pain… :V
Each piece of content looks like a single file from your screenshot. Like I said, it should be a matter of just adding it in.
According to this reddit post you should put the extras in a extras folder. So they will be recognized. https://www.reddit.com/r/jellyfin/comments/oudkvr/bonusextra_features_and_specials/
Other than that, I’m not sure what your asking.
