Resizing a flash up to the original size of the movie

I try to make movies small enough to fit on every concievable browser and screen. However, sometimes I need to make bigger movies and then put them scaleable in the browser window.
This of course works fine, i just make it 100% width and height. But how do i make it only fill out 100% when the screen is smaller than the flash movie? Because if you have a big screen and you browse fullscreen, the movie is going to be huge, the jpegs are going to be crappy and its going to be slooooow.

Just in case I’m not making myself clear I made this little demonstration for you, to illustrate what I mean.

How do I get the movie to stop getting bigger at the point where it has reached its original size?
