Need flv video to stop once loaded

Hi I have created a document which has 3 buttons. when each is pressed an action happens…loads a movie, jumps to next frame, plays video. The problem I have is when I click the Frame button, my video plays and stays.
It may be possible to tell the video controller to stop once loaded, but I don’t know the command. The way the movie is imported, the controllers are built into the wrapper but I don’t know how to stop the movie playing.
Any ideas? As much detail as poss please! (banner and frames in MyClasses folder not included),.
