why not read the manual then? http://mplayerhq.hu/DOCS/man/en/mplayer.1.txt
search for -dumpstream.

mplayer should be able to dump any mms:// stream, rtsp://.rm streams
any http:// stream. pnm and rtsp://file.mov are more difficult.

unfortunately mplayer does not save a video stream as fast as possible
on windows you should use a stream recording program like Net Transport
or Streambox VCR suite 2.0. you can learn more about these programs at:

a very detailed list of stream recording programs, what formats they 
support, and if they are freeware/shareware
