You don't need to do anything. Just point MyMovies to the proper directories and based on the folder name IE: "Transformers", It'll choose the proper title and covers and link it to the proper folders. There is a setting for "Loose, Strict, and Confirmative" when it comes to this feature.
That is unless you don't have them ripped to your hard drive at all you have is a spreadsheet... Then I have no clue!
