NetStream Video and Background Music

I’m having trouble with an issue of stopping/starting background music play back when a user clicks to start any of several external FLV files. Basically I need to kill the BG music when a movie starts and start it again when the user clicks to stop the video or it reaches the end and stops on it’s own.

This may be something simple, but I’m not an AS expert by any means.

I’m loading the video like so:

var connection_nc1:NetConnection = new NetConnection();
connection_nc1.connect(null);
var stream_ns1:NetStream = new NetStream(connection_nc1);
video1.attachVideo(stream_ns1);

And my play button looks like:

on(press){
    p14.stream_ns1.play("EAHS-High.flv");
}

Background music is here:

_root.loopTune.start(0, 999);

Not sure how to access the status of the FLV playback… Any help would be huge!
