Projector performance

Merry Christmas…

I am working on a flash presentation that will be run from a desktop as a projector. The issues I am having are, when I load swfs onto levels the movie seems to stall or stutter… it is not fluid. I thought that loading movies would help with the file size which would then improve performance but I seem to be wrong.

Would it be better to simply keep it all as one big movie? It will be running off the desktop anyway, would file size matter? My goal, obviously, is to have this projector play as smoothly as possible… but it will contain many images and an 8 minute MPEG.

As always, your help is much appreciated.
