I have a session running now at:

try that..
I'll have it up at regular intervals until the devsummit
to allow testing.

not  a lot of action but a video and audio track (low light)
and low bandwidth (often < 100 kbits/sec).
(picture of my study with no motion going on)

It should be mpeg4-video and mpeg-4 audio with mpeg4 packetisation.

for VLC you apparently need:

Preferences -> check Advanced, go to Input/Codecs->Demuxers->RTP/RTSP and check "Use RTP over RTSP (TCP)"

No idea what you need in mplayer.

Hopefully we can get precise instructions for people to watch the devsummits and 
BSDCan before it actually happens.
