Flash CS3 asssitance please

I am using streaming audio of mp3 with the MediaPlayback component, in Flash CS3,
I have 2 buttons, stop and play....
my current ActionScript is as follows:

this.btn_play.onRelease = function() {
music_mc.start(1);
};
this.btn_stop.onRelease = function() {
stopAllSounds();
};

I have it stopping properly,
however, I cannot get it to start playing again, the MediaPlayback component I have named music_mc but I don't know if I did that right, is there a different way to call upon that component? I have the audio streaming with this component, so I am unsure ho to reference it with the play button....any assistance would be great, thank you everyone.

 

I GOT IT....it was as simple as changing .start to .play
dont know why but it worked
