At this time there isn't a way for do this. I will try to add in future releases.
If you want overwrite the name of the movie with the title imported from IMDB there is a way, but you can do it only when you import the information : just go in the Import window -> Engine Configuration -> check the "Import Movie's Title" ; This should solve the problem.
I tried using the "Import Movie's Title" check box, but it does not change the name of the movie - it stays the same as it is read from the .avi file. (eg. I go to "add" --> "Read Files" --> select "Antitrust [DVDRip, Divx].avi" and it imports it into the list as "Antitrust [DVDRip, Divx]". Even when I "Import movies with default script" ([IMDB.COM] - (Full Imp. 2°G No year on OrigTitle-8 Actors-GOOD)_Alessio_Viti_8_11_2002.txt) and have "Import Movie's Title" checked the name stays as "Antitrust [DVDRip, Divx]". Am I missing a step?
