Hi, thanx for help

I have a site with multiple swfs. Each swf is 1000 pixels wide by 800 pixels tall. When I put the site up, I do not mind if the user will need to scroll up and down, but I am trying to avoid a vertical scroll. Is there a java script or action script that can make each movie either stretch or shrink vertically to fit the monitor size. Or will I have to change the size? If I must re-size, what is the ideal size?
