Distorted flash (+.net) generated images

1

After capturing a frame from a webcam, I’m saving this frame as an actual image-file.

Unfortunately, this doesn’t always work well.
See link:[COLOR=#0000ff]results[/COLOR]

I’m using the functions below.

Does anyone know what’s causing this? Can a different OS or browser cause a different outcome?

        trace("making"); 
        _root.w = 360, tmp 
        _root.h = 270;

        _root.bNum = 0; 
 
        _root.pixels=""; 
        _root.createEmptyMovieClip("imgMaker", this.getNextHighestDepth()); 
        imgMaker.onEnterFrame = function(){
