QuickTime Streaming Problem

Hi everyone,

after a long time without problems I thought I's try something new...

I want to watch the MacWorld keynote but then:

Playing 
http://stream.qtv.apple.com/events/jan/macworld/live_2004/1140/mwsf_ref_250.mov.
Resolving stream.qtv.apple.com for AF_INET...

Playing 
rtsp://a1757.v11408.c1140.g.vq.akamaistream.net/5/1757/1140/3ff9e9e8/1a1a1ae247b6e455c93f6dce3eae1a7fad107fec1b8ef356cb3da2d13b9c0a39a61d90f6265a/mwsf_keynote_250.mov.
Not a Realmedia rtsp url. Trying standard rtsp protocol.

Stream not seekable!
No stream found.


With the QT6 player it works fine, so there is a stream. But why doesn't 
mplayer find it?

Regards,
