Movies with an aspect ratio 2.40:1, 2.39:1 or 2.35:1 have even huger black bars than they normally would. On a 16:9 display I would usually crop the movie to fit the screen and it wouldn't be so bad missing the edges of the movies but on a 16:10 display you lose to much from the edges so I have to put up with the giant black bars. Movies with 1.85:1 aspect ratios look ok though on the macbook pro.
