FLV in fullscreen Projector file forces background to black

Question

I am producing a fullscreen projector (.exe) file and have some large videos that cause the background to go black when they come on the stage.
When I test the movie (not in fullscreen), it works just fine.
I've tried the solutions offered in these questions:

..still no luck

Answer 1

That's right -you mentioned the fullscreenTakeOver property and there seem to be many mentions of it in other forums as a fix, but I guess I needed a bit more handholding. I tried setting it to false using a few different methods. None worked.
This did -on the first frame after invoking fullscreen:
stage.addEventListener(Event.ADDED, onAdded);
function onAdded(e:Event)void  {
     if (e.target is FLPlayback) e.target.fullScreenTakeOver = false;
Thanks kglad for pointing me in the right direction.
