Sorting of Movie Versions

[tomthepom]

Just to make sure there's no confusion here in your example:

• The Director's Cut version is 720p?
  
• The Theatrical version is 1080p?
  

Yes

Also, try renaming the files by removing the number before their version names:

Great Movie (1986)
├── Great Movie (1986) - Director's Cut.mkv
├── Great Movie (1986) - Theatrical.mkv

Maybe doing so won't fix the issue, but it's worth a shot.

It doesn't. It should sort alphabetically but, again, the 1080p version always comes before the 720p.
