vidieos of the space shuttle never seem to have stars in the back-gound?

Videos have a limited range of light sensitivity and stars really are not that bright when compared to light reflecting off the space shuttle. If you set the exposure on the camera so that the stars were visible, the shuttle would be a featureless white blob.

They are too dim. Remember that all the pictures are taken in broad daylight. The sky is black because there is no air to scatter light, but everything is brightly lit by full sunlight as bright as a clear day at noon. Brighter actually since there is no air to dim it. So the camera exposure is set for bright daylight and the dim stars simply do not show up with such camera settings. It is like trying to see stars on a clear night from a night football game. The stadium lights dazzle your eyes making it impossible to see the stars, unless they turn off the lights, maybe for a fireworks show at half time.

The same reason why you can't see a car's grill at night when it has the headlights on. The ambient light to light the actual object is so bright, you can't even see the stars. They're so dim, the light trying to illuminate the object of interest blocks out the stars.
Look at the sky at night in the country, and look at the sky at night in a well lit city. The lights overpower the stars in the city.

Light reflected from the earth and light from the sun both obscure out any light from a distant star.
Kinda like a torch a mile away. If you shine a more powerful torch right across the front of your eyes, you won't be able to see the distant light source.

Because the light from the distant stars are very dim so cameras cannot capture the dim light of the stars in an instant.

Because the pictures were taken with the sun in view, in order to see the stars you will have to be in the shadow of earth.

Because of the sun. It has to be really dark so you could see the stars. During the day the san's rays don't led our eyes to see it.

Because this is real life.
You can't even see all those stars in a dark park at night in a city. You expect to see them in broad daylight?? You gotta be kidding me.

The only reason why we see stars from earth is because of the atmosphere, it acts like a lens to view the universe. when you see movies or live pictures from space with stars in them , they aren't real (I think).
