Frame rate problem

I created a short animation whose frame rate is 12 f/s. This animation is external flash file which is supposed to load into the main flash file.

The frame rate of main file is 20 frame /sec and my animations are 12
frames / sec. Since the animations live inside the main, the main
is over-riding animation. Is there a way to have the animation to have
different frame rate and not skip frame when it plays?

Thank you in advance,
Alice
