Proportions thrown off when movie is dragged to stage-FLASH help please!

So, I’ve made a Flash movie composed of multiple SWFs that I imported to the stage.

When I drag the movie#1 to the main timeline, the proportions (width and height) are true to the correct size and proportions, but when I drag that movie#1 into movie#2 (which is on the main timeline) the movie#1 is HUGE and stretched.

What’s going on here? Am I making sense?

Thanks for your help!
