[MPlayer-users] problem with a specific RealMedia stream

[pacman at manson.clss.net]

Expanding on my initial report from Apr 30, here is the mplayer -v output.
I wonder if the "Unknown extra header" is the problem.

I also did a -dumpstream and uploaded 1 meg of it to
ftp.mplayerhq.hu:/MPlayer/incoming as "airam.rm", but I'm not sure the
dumpstream worked correctly (realplayer 8 can't play the resulting airam.rm,
but can play the original rtsp URL)

mplayer -v 'rtsp://rx-lvl3-tex21.rbn.com/farm/*/airam/airam/live/live.rm'
