I downloaded and installed Real Player so I could watch the National Geographic one too.  I made sure I went through the file list and only gave it permission to play anything with "Real" in front of it.

I go to the National Geographic page and all that happens is that it shows Real Player as "loading".  I figure after 10 minutes nothing was going to happen, so I closed the window.

Why doesn't the Real Player show the live feed?

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
