Going to check out that suggestion!
I did follow that bottom link you sent, actually.
I have the movie directory, in which I have created a folder named ‘Featurettes’. In that folder, I have two files.
The Nightmare Before Christmas - Main movie in this folder
/volume1/Movies/1993/The Nightmare Before Christmas/The Nightmare Before Christmas.mkv
The Nightmare Before Christmas\Featurettes - has the featurettes in it
/volume1/Movies/1993/The Nightmare Before Christmas/Featurettes/Sing Along.mkv
/volume1/Movies/1993/The Nightmare Before Christmas/Featurettes/What’s This - Jack’s Haunted Mansion Holiday Tour.mkv
The “Sing Along” featurette somehow got added both as an extra, but also as the separate movie from 2013 called’ Sing Along" - which I obviously do not want.
I did want to try a Plex Dance, but the option for ‘clean bundles’ is not present anymore, as far as I can see.
