[MX]sound integration

ok now i know how to make stop and play buttons, ffw and rwd buttons
BUT
i do not know how to have the individual movie that i used to create the sound keys integrate itself with the other movie ive made, which i want to display the keys
im guessing id have to make doubble copies of the movie with what i want to have, as i did to make the buttons…but im sure there is an easier way to all of this
and i bet this is REALLY easy
but im too lazy and dont have too much time to figure it out for myself
the hard way

so
any help?!
