Controlling a loaded movie

I am loading external swfs with loader

var myRequest:URLRequest = new URLRequest(“main.swf”);
var myLoader:Loader = new Loader();

myLoader.load(myRequest);

The problem is I need to do two things.

(i) control the timeline of my loaded swf things like gotoframe(10), play stop etc.

(ii) determine what frame it is currently on.

I suppose I need to turn my loading swf into a MC then do some on the other things.

Help would be much appreciated.
