Often it is most appropriate the metadata resolve for the actual region the media was made for. (If the credits and title cards are in English, it makes little sense to be showing the localized version of the movie/TV episode).
If there is a way to mark the region/language in the filename and have infuse pick it up it would go a long way toward more useful metadata.
The below would be an example of an ideal naming convention:
Ghost in the Shell- Stand Alone Complex (ja-JP) - Season 01 - Episode 01 - 公安9課 SECTION-9
Robin Hood- Men In Tights (1993) (CA-fr)
