Confused?

I’m using this code to load a mc which contains a video into the mov2 mc on my main page. it works, except for the two things, the loadbar on ‘keithdi.swf’ doesn’t appear, and the first time the video is loaded its huged, but if you click the button the second time it resizes to the right size…???

on (release) {
_root.mov2.loadMovie(“keithdi.swf”);
_root.onEnterFrame = function(){
if (this.mov2._width > 0){
this.mov2._width = 305;
this.mov2._height = 249;

                    delete this.onEnterFrame;
            }
    }

}
