It's an umanaged switch, so all machines receive the stream... tried 
service pack 2, which didn't change anything. It's not that important to 
get it running in my small test environment - the network where 
multicast streaming will be used has a cisco layer 3 backbone with some 
unmanaged 24 port switches. There will be around 500 hosts connected. My 
concern is that the same problem with receiving multicast on windows xp 
might appear on some / most / all of the hosts (which will be mainly 
windows machines). I have yet no idea what might be the problem...  I 
first thought it might be an IGMP version  issue between the linux and 
the windows machines. But if that was the case, the windows box should 
at least answer to a ping on 224.0.0.1, right?

Thanks for your help - I still got some time for fixing this problem 
(until dec. 3rd ;))

Sebastian
