Nel mainFrame (in blu le parti salienti):


<html>
<head>
<title></title>
<script language="JavaScript">
<!-- start hiding
function avvia() {
var IE = navigator.appName.indexOf("Microsoft") != -1;
var filmato = IE ? window.filmato : window.document.filmato;
filmato.TPlay("/tuoMovieclip");
}
// end hiding -->
</script>
</head>
<body>
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=5,0,0,0"
width=550 height=400 ID="filmato">

</object>
</body>

Nel pulsante dell'altro filmato:

codice:
on(release){
	getURL("javascript:avvia()", "mainFrame");
}
le parole java e script vanno unite.
