ActionScript 1/2 :: Play Button To Launch Rtmp Movie?

I have an .fla created with a single key frame.� In the frame I have a button instance (its own layer), a layer called "act" where my actionscript is entered, and an swf FLVPlayback instance (its own layer).
�
I simply want the button to show when launched, upon being clicked to launch my movie, and the button to disapear.� My FLVPlayback points to an rmtp stream that works fine and is setup to autoplay = true.
�
currently I am using this code but the button doesn't disappear and the movie begins to play before the button is pressed.� I have also switched the movie to autoplay = false but pressing the button does not play the movie.
�
the code on the "act" layer is (my_btn is the button and my_mc is the movie):
�
my_btn.addEventListener(MouseEvent.CLICK, btnClicked);function btnClicked(e:MouseEvent):void{my_mc.play();}
