loadMovie, to fit to window wo/ showing boarder

[LEFT]here is a weird problem, that has me stumped, it seems like it should be easy, but i just can’t seem to figure it out…
here goes

i am working with a team of animators who make cartoon music videos, the videos range in size from 980x1280, to 1400x1600, i then take these videos and load them to a movie clip in my “video room” .swf,

the code to load the movies is

on (release) {
_root.screen.loadMovie(“video/dvd_avideo.swf”, this);

the code to resize the vidoes goes as such

onClipEvent (load) {
_root.screen._width = 320;
_root.screen._height = 240;

now the video resize just fine, the problem is the entire area of the video shows, even the items that are located outside of the stage,

i don’t know why the vidoe is showing items located off of stage?

is there a way to crop the videos out so only there stage area shows when called into my .swf
