Hi,
As I mentioned in the .58 and .59 threads (which are both outdated and locked now), when I move and rename a newly imported video file using the Rename, Move & Copy Files dialog (F6), the video file itself gets moved and renamed, but the cover art image file only gets moved, but not renamed, resulting in the cover art disappearing from the library. Even after renaming it, I have to re-attach it using Cover Art - Add from File to get it to show up. (After renaming the image file, it appears when I hover over the file in Standard View, but isn't visible in the views, in Standard View nor Theater View.)
It has been like this at least since 20.0.50, which was my first MC 20 version. It worked in MC 19.
I've so far only tried this getting cover art for TV-series episodes using Get Movie & TV Info. For my movies, i always have to get the cover art manually using Google Images, since I want the covers to be from the format I import, like the Blu-ray cover if I import a Blu-ray movie.
I do have to use the Get Movie & TV Info to get the correct episode name before I move and rename the video files, because I want the episode name as the filename on disk.
