stop();

MenuItem1.onRelease=function{ loadMovie("peli1.swf",cargador);}

MenuItem2.onRelease=function{ loadMovie("peli2.swf",cargador);}

etc...

gracias, lo he probado y me da el siguiente error:

**Error** Escena=Scene 1, capa=Actions and Labels, fotograma=1:Línea 185: Se espera nombre de función
MenuItem1.onRelease=function{ loadMovie("peli1.swf",cargador);}

**Error** Escena=Scene 1, capa=Actions and Labels, fotograma=1:Línea 187: Se espera nombre de función
MenuItem2.onRelease=function{ loadMovie("peli2.swf",cargador);}

que tengo que hacer?

te faltan los parentesis

MenuItem1.onRelease=function () { loadMovie("peli1.swf","cargador");}

MenuItem2.onRelease=function () { loadMovie("peli2.swf","cargador");}
