Just tried the URL with Firefox, using the Mplayerplug-in on my FC2 install,
and it streams fine on my dialup connection.
Firefox shows it as being http://wrfg.org/listen.asp. Which of
Mplayerplug-in's plugins it's using I've no idea, without booting another
distro, where I have an instance of Firefox in /usr/local (for testing out
which plugins are needed), and has no plugin symlinks setup.
Perhaps I'll bootup Lenny, and see if I can get Gstreamer to play this URL,
but there are so many packages for Gstreamer, it may take some time.
