Based on some screenshot found on App Store and:
viewtopic.php?f=1&t=1228there should be some option to Scan video files, but I can't find it (Tools -> Scan my video files).
When I select 'Automatic file scanning' option found under 'Manage your video files', nothing happens.
I'm using v3.26.6 Life for OSX.
So how do I associate existing files with the movie items?
