Movie clip (start & stop)

okay i made a (.flv) file and imported it into flashMX and put it inside movie clip symbol… it plays fine, but loops over and over forever… how do i play it just one time!? and how do i start, pause or stop it from a button on the main stage.

the mc variable is local inside the symbol, and isn’t visible from the main stage… so how do i go about doing this…

no looping… and a symbol movie clip control from main stage…?
