Why is the Director's Cut longer?

Rating: 9/10 (19 July 2005)

It makes me confused. Why is the director's cut longer than the Version You've Never Seen. Are there deleted scenes in the version you've never seen, or is it the credits? Why is it longer? I thought that the version you've never seen has all the deleted scenes. Then why is it shorter? Did i miss anything. If I missed something could you tell me. Just tell me why is it shorter? The new version should be longer. But why is the old version longer in terms of running time. Are there scenes removed from the Version You've Never Seen? I think it's nearly 20 minutes or less, compared to the director's cut. Why should it be shorter. The deleted scenes were found in the new version, but why is the director's cut still longer.
