Shar,
Typically you will not see stars in the video simply because there light is below the resolution of the Camera being used. Just like if you walked outside at night and clicked off a few shots of Stars with any old Camera you'd end up with pictures of nothing but dark sky.

I get that but, look here _javascript:cnnVideo('play','/video/tech/2006/09/19/vo.shuttle.debris.nasa','2006/09/26');
I thought that was it because if its that dot ,its just crap on the lens.In that shot
you can tell ,it moves with the camera.

That's so wrong i'm sorry... it just has to do with exposure time of the cameras. Due to the bright sunlight reflecting off the Earth, the shutter speed needs to be quick to get a good exposure. To get the faint starlight to expose on film, you need a long exposure time. It's as simple as that.
If light needed air, how would we get light from the Sun or see stars?
