[MPlayer-users] real video over rtsp

  The header on this file says it's only 179 seconds long, so apparently
  MPlayer's working OK as far as playing it.

  The dumpstream works fine for me, and it looks like you're doing
  everything right... Hmm. Have you tried the latest CVS version? I'm no
  expert, but it's all I can think of. Hope this helps. :)

  	Take care,
