You can try to introduce a slight blur in your video editor, that will sometimes take out most of the jitter (called aliasing). If that doesn't work, then you'll need to magnify the original material. A little zoom in and panning may still allow the viewer to understand the illustration.
Line widths/spacing less than three or four pixels on DVD will usually alias on TV displays since they only have about 400 lines resolution on the screen.
