Roll out, roll down effect help

Hi,

I’m trying to incorporate a “roll-out” effect. I have 3 projector screen images, each one progressing until the entire projector screen is laid out, but not sure how to create it. The ultimate effect I would like is to have the screen roll down. I tried both motion and shape tween between the images but don’t quite get the effect I’m looking for. Esp with the shape tween, it repeats the image too much (because I “break apart” my image/mc). Any suggestions or links to tutorials or samples?

Thanks
