Different SWF's interacting... question!

Hi there

I have 2 flash movies on the same html page. they are completely seperate swfs. One is the nav, the other is a sample video. when the sample video plays, we want the ambient sound of the nav to stop.

Is there a way to do this? By having a button pressed in one swf stop the sound in another?

I’ve heard about local connections and am researching it now but could really use some help.

thanks much!
