Loading a SWF file from a movieclip

Hi all!
Got a fairly simple question to ask… Now loading a swf file into the main timeline with loadMovie (to a mc_holder) is simple but I seem to have trouble when the button is contained in a movieclip… In the main timeline I have a mc_holder say line 1, the button to activate it needs what code to import it to that mc_holder? The mc_holder isnt contained in the movieclip and is contained on the main timeline… www.tntvids.com/basic You can see the movieclip with the button…

Thanks in advanced
