Oops, forgot to reply to this bit...
What exposure time were you using for this? If it was a ToUcam at 5fps then that would be around 200ms which explains why you were able to see an image. You'll probably find that much shorter exposures will give you more detail, mostly because of less time for atmospheric blurring, say exposures around 100ms or less, ideally less than 40ms. This also means that the image gets a lot dimmer and you might find that you have to reduce the magnification so Jupiter is no longer a problem on a 640x480 ccd.
Sorry, I hope that's not too convoluted an explanation for this time of morning...
