Downloading a mms audio stream

[Kenneth W Cochran]

How can I download an audio clip like this for subsequent playback?

mms://wm.npr.na-central.speedera.net/wm.npr.na-central/atc/20031017_atc_07.wma

I have mmsclient but it doesn't seem to be working.
That being "asked," how do I set-up things in Mozilla so I
can listen to and/or download audio and/or video clips?

OS is RELENG_4 as of 2003/10/03 (4.9-RC)
Mozilla is 1.4.1 from -ports, built from source.

Pointers to documentation, FAQs, etc. are welcome. :)

Thanks,
