Newbie question: stop, play, rewind buttons

hi all, i am doing the website for an architectural company (apexstudios incorporated: www.apexstudios.com). if you go to projects>single (or any of them for that matter) and click on a video you will see what i am doing.
the question i have is: how can i make buttons that i can stop (pause rather), play, and rewind (say 4 seconds per click). i know how to make buttons and i have an OK knowledge of AS…so any help would be real appreciated. thanks alot -stone
