Loading swf of different dimension

[FONT=Arial]Hey all!

New to flash and the forum so be gentle.

Here is my issue…

I have a main navigation flash file (1000x550) dimension in which I am loading external swf’s built to a 1000x400 dimension. I am using my loader to pull these files in and it works fine. Problem is that my empty loader clip (which is the same dimension as the external files), yet when I preview the whole thing, the external files “spill over” content that was off of the stage area (example, the area of a photo that is off of the stage).

Okay, that sounds rambly, but how do I contain external swf’s to the stage area and not show the junk that spilled off of the stage?

Help!

and thanks!
