Tweening Dynamic Movie Clip

I am having a problem getting an instance of a movie clip to tween on my main timeline.

I have a movie clip that is used to dynamically load an image into it. I have all the code working for the image load, so I am all good there.

I wanted to motion tween the instance I dragged out to the main timeline. Make the whole clip move down 100 pixels. The editor lets me create the tween and key frame fine but when I run it, the movie clip does not move and sometimes does not show the picture at all. One other thing to note here is the frames between the keyframes in the tween do not show the little movie clip circle like the keyframes do.

I am also trying to do the same thing with a movie clip that has a dynamic text box in it as well. Again, nothing shows up once I try to tween the mc instance. And yes, I embedded fonts.

Thanks for any help in advance.
