Oh right, that actually makes sense, since you can't repeat the header
for each newly connecting client like what unicast servers do. Kinda
ugly, but what do you expect...

from last year made me think you didn't)? :-). If so, please tell me how
(mplayer - or vlc, or anything - didn't manage to even parse the nsc
file for me, let alone play the multicast udp stream when specifying it
on the cmdline).
