I ran across a post on Lifehacker about this very subject, and there seem to be several apps that would work. My primary criteria:
- "Autofill." Or whatever you might call it. For example, if I just typed "Godfather" it would give me options to select all three of the movies and fill in the rest and format it. And once the movie is selected, the app would update the entry with the stars, director, writer, etc.
- Work well with TV shows, too, since I seem to have a lot of those on DVD as well.
- Export to a list that you could keep handy, beside your movie collection.
