Turning a NetConnection off

This code is on the opening frame of one of my Flash files:

var myConnection:NetConnection = new NetConnection();
myConnection.connect("rtmp://fvss.playstream.com/fvssod/myclient");
var myStream:NetStream = new NetStream(myConnection);

myVideo.attachVideo(myStream);
myStream.play("iLoveLALong");

It starts this song “iLoveLALong” as background music. Works great. But now I need to turn the music off when I jump to another frame in the Flash doc.

Can anyone suggest code that will do that, either with frame code or button code?

Thanks.
