Connecting 2 swf files problem?

i made 2 swf files. and first one loads another. but second one could’t connect first one. second one uses MediaPlayback component. and if the second one’s movie finishes how can play first one’s frame. and here is my code.

first swf’s code
loadMovie(“video1.swf”,"_level2");

second swf’s code
mc_video.complete =function(){
unloadMovie("_level2");
_root.gotoAndPlay(10);
}
and what is my problem?

I do not see the point of that 2nd code??
delete that 2nd code!!
