Hide dynamic flash video from stage when leaving frame?

Hello all,

I am still working on this flash presentation and I have coded a dynamic video player that calls on a url to play an mp4 file.

The problem is that when I leave the frame which I have designated for video, the video still remains on the stage over the content on the other frames.

Now, I have experimented with things such as removeChild but with no luck.

If anyone has suggestions about how to make the video visible on one frame, or to make it stop playing on other frames, I would appreciate the input.

Thanks!

Here is my code if it helps.

var alreadyExecuted:Boolean;

if (! alreadyExecuted)

{

  alreadyExecuted = true;
