External movie loaded doesn't start

I’m loading an external movie from other movie. The movie I’m loading has an animation, but it doesn’t start when loaded from other movie. The animation only works alone.

I’m using this code to load the external movie:

_root.createEmptyMovieClip(“conteudo”, 1);
loadMovie(“abertura.swf”, “conteudo”);
conteudo._x = 2 ;
conteudo._y = 0 ;
