Hmm, well, iirc it was a 8mbit stream, but I'm not sure if I also tried 
a 3mbit stream, but I bet that still wouldn't have worked reliably. Not 
much difference anyway. Because no, not my switch, dvbstream needs 
replacement. Multicast simply sucks, what you want are peer to peer 
connections. My switch has no problems handling these at 100mbit. No 
SoHo switch has. But multicast? There's a reason IPTV ISP's don't switch 
you know.. For Multicast you should use satellites, DVB-T transmitters 
or (coaxial) VHF/UHF cable infrastructures. Not UTP with SoHo switches!
