I am unsure of exactly what you are talking about? If you are talking about the special features (ie Directors Cut, Deleted Scenes, etc) then you just use your mouse if you are using your computer, or the remote if you are using the DVD player.
Please be a little more specific when stating your problem in the subject line, as "I need help" usually won't get you much help, people will just look it over.
So please be just a little more specific as to exactly what you are trying to do, and we will help you as soon as we can. Thanks.
