These movies are created every day from the weather camera. They show
the entire day's weather in a few minutes. The files start out during
night, so if you see a black image, just wait a minute or so
for sunrise to begin.
The 'click here' links download the entire file. And this seems to work in Windows Media player but you'll have to wait for the entire file to download. The mxu links attempt to stream the file from the server, so you should see images sooner. I've been able to get this to work with Real Player, but Windows Media Player only seems to play complete mpeg movies.
