Thanks - then the issue is more understandable. The interesting thing 
would be to know why this one doesn't work for you over UDP, while other 
RTSP sources probably work fine for you over UDP - or do they? Also, 
anyone that experiences the same problem - does VLC or Totem/gstreamer 
receive the packets over UDP or TCP?
