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!
