Low - med - high -quality script question!

Ok, I have a fairly large animation sequence that in order to keep it from chugging through the frames I need to publish and run the quality at medium… I am ok with that for the intro animation…

BUT when I get into the main navigation section of the site I want the movie quality to jump to high as medium quality is compromising the quality of the illustrations considerably…

Question… Is it possible to change the movie quality settings with actionscript??? if so any samples would be great… any feedback at all would be greatly appreciated.
