loadMovie relativity (header for site)

The goal is to have a header that i can include in different flash movies.

I have created a header that loads its contents from an xml file and then displays everything. _root.loadMovie(“header.swf”) will load the movie into another flash movie, but nothing else on the stage shows up, so i try to load it into a mc called nav, and it screws up all of the paths and nothing draws out correctly. what do i do about this problem? the relative paths in flash confuse me enough, so i don’t think it would be possible for me to change the paths, unless someone has a little instruction there.

Help is much appreciated!!!
