Resize External .SWF in a .FLA

Hi,

I need to load an external .swf (600pixels by 600pixels) into a .fla but I need shrink the size of the .swf to 200pixels by 200pixels.

Can someone help.

I created an empty shell movieclip using menu called my_shell and then added the following code to a frame:

loadMovie (“my_movie.swf”, “my_shell”);

This loads the .swf but at full size 600pixels by 600pixels.

How do I force the .swf to be loaded and resized down to 200pixels by 200pixels?

Thanks
