loadClip into _root?

I want to load my movie into _root.

I have preload.swf which all it is is the preloader and I want to load home_page.swf. If I loadclip into a movieClip its fine, but not if I do _root…or alternatively, ‘this’

Is it possible?

The reason I want to do _root, is the site I am working on, the previous developer on it used _root everywhere and I dont want to have to go and change everything that has _root in it.

Also, anyone know why my movie starts playing when its only say 50% loaded?
