Well after months of happily using Mezzmo I started having an issue with not able to open the GUI - kept on crashing. Seems databases problem and only way to resolve was to delete all the databases. So lost all my playlists, permissions, media device settings and worse of all was the thumbnail association.

Recreating playlists, permissions and media device setting was not a major deal but I now need to go thru every movie and TV series to reset the thumbnails - have 1,093 video files

So there needs to be a backup config feature - which either gives option to manualy back up at a specific point in time or allows you set set a daily, weekly, monthly restore point.

I love Mezzmo but air was blue tonight!
