Thanks Aspiro! That worked like a charm! I created a MovieClip based on the background I had and then selected every frame in the animation, Copy frames, entered into the MC and Paste frames. Once I did that, I deleted the original animation frames and voil! Thanks again!
This function resizes all you objects keeping they aspect ration and using symbols 0.0 point as pivot. Sometimes it means that you have negative scale which mean mirror flips on one or two axises.
The better choice for you will be place all your content (animation and stuff) inside new MovieClip and resize it by tranform tool.
You are welcome
