Motion Blur lmc_tween

Hello.
I have a little problem with my as, i would like to add motion blur to my animation tweens, how should i do it (?), here is part of my code:

[AS]
import flash.filters.;
var myBlur:BlurFilter = new BlurFilter(0, 0, 3);
///////////////////////////////////////////////////////
function slideIn(){
show_content();
var overlap:Number = .05;
var columns = 3;
var rows = 7;
for (var z:Number = 0; z<myPanels.length; z++) {
scroller.container[“xml”+z].filters = [myBlur];
scroller.container[“xml”+z].img_hitArea._alpha = 50;
scroller.container[“xml”+z].tween("_x", (z%columns)panel_spacing+40, .5, easeType, overlapz);
scroller.container[“xml”+z].tween("_y", (Math.floor(z/columns)%rows)panel_height+70, .5, easeType, overlapz);
scroller.container[“xml”+z].tween("_alpha", 100, .5, easeType, overlap
z);
}
[/AS]

I found here some code that **devonair **wrote, but i dont understand it.
Thanks in advance for your help guys.
