I am sorry it took me so long to write an answer!
English is (obviously) not my first language. I have some movies in my library which got some really strange official translation of their names into my language. eg: "The Sum of All Fears" --> "Der Anschlag"(translates back into "The Assault").
Since i am using imdb as movie scraper, xbmc only ever lists the english names of movies found, which is just fine with me but sometimes I can't for the life of me remember how the movie was called in english, just because someone in my country though it would be a great idea to give it a completely different name
Searching for actual filenames would allow me to name my files appropriately and get the translated names this way.
