That's not exactly a bug, but more like not-well-functioning-thing, fairly important with some libcad scripts.
In practice, you can't display different track covers for the same album, and that's quite horrible (and stunning, VLC should be the most powerful player in every range) problem, especially for those who have a lot of tracks with different covers each other, even in the same album.
Tried in a lot of ways. Modding some files and VLC's configs, locking the /artistalbum/ folder (that's the problem, /arturl/ has no problems 'cuz there are no album references) but then I get just a black screen, or the cone.
And I don't want to leave this just for a little problem. There are some solutions? I hope so.
