External swf and flv

hi, I have a problem, I am using this http://www.kirupa.com/developer/mx2004/transitions.htm

And my question is, can i load my intro automatically using an external swf? And right after the intro, my swf in button 1 will load.

And another question, for my intro is it possible to use an flv and once it’s done, the swf in button one will load?
