Flash :: RemoveChild So Can Load New FLV_Player

I am making a flv player with playlist that has and English and Spanish section. The English is the default section and that works very well but when I click "Spanish" button I am trying to remove all the children that were added at start time and run two new functions that load my Spanish data.

The only thing is that removeChild is not working. I can hear my Spanish video load but the English one is still playing in the background.

I need to completely remove main_container.addChild (my_player);

here is the function that should do it all:

function playSpanish (evt:MouseEvent){
main_container.removeChild(my_player);
gotoAndStop(2);
trace("IN SPANISH");
}
