With the last error I reported, it seemed video server reported a broken
SDP.
But now I've changed the video server (now it's Helix) and have another
problem.
I've made some test using directly liveMedia Library.
It seems the problem isn't locale to livedotcom library, neither to
broken SDP.
In fact using openRTSP the video gets received, while with VLC 0.7.2 it
doesn't.
I past both logs here.
What do you think?
