[edit] Saving streaming content (rtsp/mms protocol)

Every now and then you might encounter videos on the 'net which you can't simply save, because they're so-called streaming content. They use the mms or rtsp protocol, and their URI starts with mms:// or rtsp://. Using mplayer, you can easily save them:

mplayer -dumpstream rtsp://example.com/foo.ram -dumpfile some_name.ra
