Autoplay = false - video still plays first few frames then stops

Hello,
I am trying to put some video up and am using the mediaDisplay component.
I have unchecked Automatically play in the component inspector but the video still plays about 15 - 30 frames of the video then stop.
I have also added the actionscript for turning auto play off
myDisplay.autoPlay = false;
myDisplay.setMedia(“http://www.halk.ca/flv/intro.flv”, “FLV”);
(I have tried putting autoplay before and after setMedia, same result. I have also tried pausing it automatically…
myDisplay.activePlayControl = “pause”;
still not working, does anyone know why this is happening and a work around? am I missing something?
thanks,
JH
