Access netStream from inside a loop

I have three movieclips i would like to play one after another.

I have them loaded into the flash using bulkloader but i can’t access netStream for any of the loaded videos.

Is this possible and what am i doing wrong?

This is my working code so far:

any help would be great

private function videosLoaded(evt:Event):void {
	trace('all videos loaded');
	for (var i = 0; i < 3; i++) {
	movieHolder = new movieHolder_mc(); = i;
	movieHolder.x = i*512;
	var file: Video = new Video();
	file.width = 512;
	file.height = 286;
	// get the nestream from the bulkloader:
	var theNetStream: NetStream = videoLoader.getNetStream("video_"+i);
        //disabled this to stop the movies from playing but need to access this from outside the loop.
        // doesn't seem to want to work
