PS don’t forget to set the visibleVideoPlayerIndex property to the same index as the active index!

I guess you could extend MovieClip with a EventDispatchingMovieClip like so:

import mx.events.EventDispatcher;

class EventDispatchingMovieClip extends MovieClip{

public function EventDispatchingMovieClip(){
EventDispatcher.initialize(this);
}

public function dispatchEvent(){}
public function addEventListener(){}
public function removeEventListener(){}
}

(sorry about the formatting, I thought I had a code formatting plugin but it seems to be malfunctioning ).

Then, whenever you need dispatching, instead of extending MovieClip, extend EventDispatchingMovieClip… Purists prefer composition over inheritance, but let’s face it, this was a hack to begin with
