Close loading video swf or flv

programming flash
1

So i have a site with three video players, one swf and two flv. My code does fine to unload each player and load the request but i have a problem if the user clicks on a second video before the first has loaded. It ends up playing both videos.
So i put some code “contentLoaderInfo.addEventListener-open” to be able to close the loading video if needed. is this the best way?
Note: this is only a small section of code, if more is needed let me know.

thumbLoader1.addEventListener(MouseEvent.CLICK, thumb1click);
[COLOR=“Red”]test_loader.contentLoaderInfo.addEventListener( Event.OPEN, thumb1click );
loader.contentLoaderInfo.addEventListener( Event.OPEN, thumb1click );[/COLOR]

function thumb1click(event:MouseEvent):void {
vid_player = 1;
playVideo();

    if(loader != null)		
{
loader.unloadAndStop();
    [COLOR="Red"]loader.close();[/COLOR]
}    
if(test_loader != null)		
{
test_loader.unloadAndStop();
    [COLOR="Red"]test_loader.close();[/COLOR]
}

}
