Here are two graphs of this TCP connection:
http://christian.tsotras.free.fr/mplayer/
(the two PNG files)

The throughput and the time-sequence graphs show that the capture lasts 170 
seconds (I stopped it myself), so the streams following the advertisement are 
embedded in this "binary stream". No new request in clear text.

I've also put online in this same URL the original tcpdump trace. Maybe you 
could play with it.

Yes, I think it's (b), and maybe it filters the client program: windows OK, 
anything else: bye bye.

I tried to play with mplayer sending the "NSPlayer..." header in his request, 
but no result. I did not worked a very long time on it to be sure to have 
tested all possibilities though ...

Interesting. But as you said, is this problem worth the time spent for only a 
few users ?

Thanks for your help.

I've no idea what I could do more, except re-learn C for one year, and modify 
mplayer's code for another year.   :-/
