When I get back home to my computer, I'll try and remember to post a pic of my starfield. It actually looks real... it has various sizes of stars - some so faint and some that really stand out.

If you are viewing the stars from space, you don't want them to twinkle, because they only twinkle due to the Earth's atmosphere warping the light. In space, most of the stars (with an exeption of few) are static.

If your camera is going to be still, then you would probobly be better to paint a background in paint fx, but if you need the stars to move in the background, then make a sphere, flip the normals and apply some sort of texture to it.

I'll post a pic of my stars soon. =]
