Matter of AS

Hi everyone,

Well,i am not very good at AS and everyday i have a new issue to think of.
On a site i am doing this:
1)Preload the main scene(frames 1 and 2 with AS)
2)Main scene is :bg tweening + 1 banner (mc) + animated menu(mc)

To open the new mcs with the contents(links,pictures,whatever) i am using loadMovie.

The thing is i want to have an empty mc to load an mc (with tweening etc) .To do this i believe i have to add _root.emptymc.loadMovie(“whatevericallit.swf”); in the main timeline on the main scene and not inside a mc,right?
If i do like this i will have the scripts for the preloader in the main scene and will have to add the scripts for the loadMovie in the _root,right?

How would i do it?

Thanks for any helpfull time spent answer.
