This may be more of an HTML question. But how do I put a banner at the bottom of the page with a flash movie but still allow the movie scale to the user resolutions?

I currently have to movie play with the orginial size I set in html at 800x600. But when I load this on a system with 1280x1024 the movie is very small. I would like for it to scale to the larger screen but still be able to put an html banner under the movie.
