Using Windows Movie Maker to make stop motion animation?

I am using WMM 2.1 with my students, we are creating stopmotion animations. I imported their digital pictures into movie maker, reduced the transition and duration time to .125 and .25 respectively. When we try to preview the movine in Timeline, it skips all of the pictures, like it is lagging out.

I turned the project into a movie to see if would play correctly, and there are lines running through it and the picture is jerky.

Help!!!
