How to save a streaming video with mplayer

[zhaoxmustc at gmail.com (zhaoxm)]

Hi,everyone
	I can play a streaming video with mplayer, just like 
		$mplayer mms://...
	Since there are a lot of streaming videos that I like so much
that I want to save them in my hard-disk as a avi or some other
formats for later digesting, can I do that? How?

    Thank you
