Ok...
It could be better with a bit of sound.
About the looping movie:
Stopping the movie is simple: under actions of the end of your movie, put: stop();
You have to create a button (the replay button), and add this under "Actions":
on(press}{_root.gotoAndPlay(<STARTOFM OVIEFRAME>);}
Replace <STARTOFMOVIEFRAME> with where your movie starts; usually 1.
