HELP - Printing Loaded SWF's with main timeline

I have a problem with a flash movie I am trying to add a print button to. I am loading a separate SWF and a JPEG from an external source into two separate movie clip_holders. These are loaded dynamically based on a variable.

Everything works fine with the proper images loading but when I try to print out the root timeline using:
printAsBitmapNum (_root, "bmovie") ( I also have a bounding box frame set up)

Everything prints except for the loaded movies. I have tried all I can think of...Any thoughts?
