Controlling MediaController?

Hello everybody,

I'd like to have a button that stops a video playing in a MediaDisplay. I know it can be done with de MediaController but I need an additional button for that.

1. my_movie.swf loads video.flv through a MediaDisplay component: "display".

Code:

---

Code in "display":

on (load) {

        this.associateController(this._parent.controller);
                       
}

URL parameter: video.flv

---

"controller" is the MediaController associated with "display".

2. main.swf has a movie clip in the main timeline: "my_mc".
my_mc has a button ("load_btn") with this code:

Code:

---

on (release) {
        loadMovieNum("my_movie.swf", "1");

---

3. main.swf has a button ("unload_btn") in the main timeline that unloads whatever is in level 0.

Code:

---

on (release) {
        unloadMovieNum(1);
}

---

Here is my problem:

unload_btn unloads my_movie.swf but the sound doesn't stop playing.
If a click load_btn again just "controller" will show up over my_mc and the audio of my_movie.swf will continue playing no matter wich button a click.

Well, I hope some of you could help me with this.

Thanks in advance!
