Comment 6 for bug 600682

All of a sudden, vlc now does open the stream:

~$ vlc rtsp://wm.media53.kpnstreaming.nl/kpn=TweedeKamerL=Plenair101
VLC media player 1.0.6 Goldeneye

Totem works, too, but mplayer doesn't and neither does openRTSP (attachment):

In the mean time, vlc was updated to 1.0.6-1ubuntu1.2; I'm still using livemedia-utils 2010.02.10-1. I assume a fix was released in vlc.
If the problem was caused by liblivemedia though, I can't explain why vlc now does work, while openRTSP doesn't.

Please note that I tried only one rtsp stream, as I couldn't find any other. Might it be possible that the stream was corrupt is now fixed?
