Well I stand corrected.? If I turn off IGMP snooping in my switch, put a UDP symbol in my Crestron MC3 with an address or either 239.0.0.200 or 239.0.0.255, and then use Wireshark to capture all the multicast traffic,? the MC3 indeed sends out either 239.0.0.200 or 239,0.0.255 with the correct destination mac address of 01-00-5e-00-00-c8 or 01-00-5e-00-00-ff respectfully.? BUT, Wireshark reports the packet is malform.? If I send a multicast stream from my laptop using ffmpeg, the packets are not malform.? So it appears that at least the MC3 if formatting the packet incorrectly.
