Loading A New Movie In A New Window

I am sure that the answer to this is somewhere in this forum, but I may not be using the right search words. I am creating a Demo CD for my company using Flash MX. I am familiar with loading movies using various levels. I am trying to code a button to open a new Window playing my flash movie. I have built a flash movie that is approximately 400 x 400 in size. My main movie is 800 X 600 an has a button that when pressed should open this new movie (the 400x400 one) front and center in the user monitor.

Some posts and tutorials have addressed this question specifically, but as it pertains to the web. I am building this for a cdrom and not the web. Can anyone tell me which method will work for this.

LoadMovie?

LoadURL?

FSCommand?

Or none of the above?

Thanks in advance.
