World's First Large-Scale Ogg Theora Stream
Maybe this has to do with the fact that conference rooms in the middle of the night with their lights switched off are not exactly an exciting scene to stream live?
In other words: the streaming servers are probably switched off. Try again tomorrow morning (Norwegian time).
I've watched some of the live streams yesterday and today, and overall it was quite impressive (the only comparison I have are realplayer streams of recorded TV newscasts at roughly the same bitrate, which always freeze to refill the buffer at some point).
