swfmovie->setbackground() sets the background color. Why is there no rgba version? Think about it. (Actually, that's not such a dumb question after all- you might want to let the HTML background show through. There's a way to do that, but it only works on IE4. Search the http://www.macromedia.com/ site for details.)
