How to tween multiple movie clips within a single layer

Hi,
I need help:
i want to have two different tweens on different movieclips within same layer…but what happens is…it groups both the mc into a single graphic…and applies tween for the entire graphic…and also i loose the Mc instance.

how can i achieve diff tweens on diff objects within a layer??
More important is dont want to loose the MC instance

thanks,
Vivek
