Steve,

It is jerky because you're forcing the computer to rewrite many pixels 

every frame, especially as the car gets larger. Less detail in the car will 

help. Keeping the car smaller will help too, or limiting the size of the 

whole movie in the browser window. Gradients are particularly demanding 

when tweening. It's possible to get a little more speed by breaking down 

the motion tween into a frame-by-frame animation (highlight all frames and 

use Insert>Keyframe), or even by breaking the car apart (Ctrl-B on PC) so 

it's no longer a symbol. This will require less computation by the playback 

machine since all pixel information will be sent along with the movie. The 

trade-off will be a much larger movie size (longer download time, less 

likelihood of ininterrupted streaming) because you're no longer using 

symbols and the Flash player's ability to interpolate pixels.
