Flash Movie as Background

Hi,
I have a flash movie which basically has around 10 frames and I am moving between the frames by pressing the down and up arrow keys from the keyboard by adding an action listener.

Now what i want is that when i am moving i always want a flash movie to play in the background.
I tried using netconnection and attachmovie but it only plays at the first frame. How can i have a movie which plays no matter where i go in the frames.
