I have an external HDD with 3500 films on it. When I use the scan drive option everything goes well with the active playlists going from A - Z. The weird thing is now after scanning the whole drive there is no "T" active playlist. There are however all the films beginning with "T" under the all video files tab. It used to work fine but for some reason now its gone. Have tried maintaining libary many times, resetting the database and even unistalling and reinstalling mezzmo.
