Problem with the dropShadow filter

Hi,
I have the following code applying the dropsahdow filter to two different movieclips. For each instance I try to apply two different alpha values for the filter. But when I test the movie, both shadows are equal in alpha value.

I am still learning F8 and its new features. Can anyone help me?
Thanks a lot.


import flash.filters.DropShadowFilter;
var dsf:DropShadowFilter = new DropShadowFilter (20, 45, 0x000000, 10, 5, 5, 1, 2, false, false, false);
movie1_mc.filters = [dsf];
var dsf2:DropShadowFilter = new DropShadowFilter (20, 45, 0x000000, 100, 5, 5, 1, 2, false, false, false);
movie2_mc.filters = [dsf2];
