Some flicker may be unavoidable if the resolution of the animation is too
low - each star object (sphere, or whatever) may cover too few pixels to be
sampled properly, but making the star objects too big obviously produces
stars that don't look like points anymore. You might want to experiment with
the star object size. Anti-aliasing will improve the situation
because of the increased sampling across the star, but a good solution
would be to increase the animation resolution (I guess that this not
possible with a made-for-TV animation!).

The white-dots problem; I suspect that this may be a result of using spheres
as the star objects. You could try replacing them with onion-textured
transparent discs, for one example. Each disc would have a smoother
drop-off to the background than a "sharp-edged" sphere.
