Multible DVD in one movie

Hi

Scraper "problem"

I have a movie "Bryggeren" (http://www.imdb.com/title/tt0115119/) wich are in 3 DVD's. I've placed the 3 movies in one folder called "Bryggeren". My question are now how do I maxe theese 3 DVD's into one movie? If I say all 3 are the same movie, then this movie will appear 3 times in my list ..
