Mediainfo.dll is not yet supported so will not give you any information (planned for release 0.8.0)
Where does the plugin get the movie length from? A lot of my movies are found and the movie information is correct, but the duration is 0:00 quite often.
by adding mediainfo.dll support your problem would be solved.. instead of relying in imdb grabbin.
Unfortunately that will not help for complete dvd image files (iso/bin). At least I don't think that mediainfo will be able to do this.
Not even sure if it will work on ripped DVD folder structure since there can be extra material etc.
But please correct me if I am wrong.
All I really need to filter, is between watched and unwatched movies.
Mate, you must have/watch so many movies so you cannot keep track of them
