Transition Effects Between External SWFS

hi guys…
Recently i went thru a tutorial posted in KIRUPA.COM abt Transition Effects Between External SWFS

here is the link http://www.kirupa.com/developer/mx2004/transitions.htm

… But the external swfs only load when a current running movie stops. suppose if we want external swf with transition to be loaded when a current movie is playing how can we do tht…

Can somebody Help
