This is the nature of CU-SeeMe. The blocks are sent in random order, and
at 14.4k you're probably not getting the full feed. Check the stats
window under the NASA image and you'll probably see some reference to
packet loss. Given time the screen will complete. I've gone up to 28.8
since last week and the quality has improved, though it's not perfect.
Read the FAQ there's much more interesting things to be found (including
the answer to this question...)
