I’ve never had success using the Plex “editions” feature. I can add an edition, and that edition will indeed show up as a separate movie, but it has the side-effect of making all extras (trailers, featurettes, etc.) invisible from both entries for the movie.
There is a long thread elsewhere on the forum about a similar problem, but that involved the use of .plexignore, and I’m not using that anywhere on my server.
My most recent example: “The Wonderful World of the Brothers Grimm” (1962) has two versions, a “letterbox” version and a “Smilebox” version which tries to recreate the original Cinerama curved-screen experience. I create an entry which includes only the letterbox version and all the extras from the Blu-ray, and all is fine. But as soon as I add the file
The Wonderful World of the Brothers Grimm (1962) {edition-Smilebox Version}.mkv
to the folder, all extras become invisible.
Except for the “.plexignore” thing I didn’t find any other threads about extras disappearing, so maybe it’s just me, but it certainly seems like a bug in the scanner or server.
I’d appreciate any help in tracking this down. Since I can’t use the editions feature I’m just adding those alternate editions as extras of another sort (“featurette”).
