I have this replicated on 5 machines at this point. I'm running VLC 0.8.5. My working theory at this point is that the kernel isn't giving the packets to VLC. Does anyone know how to ask the OSX kernel what multicast streams are subscribed to what applications? Is there any other multicast debugging...

vlc on a linux box transmits a multicast feed to Windows boxes running vlc which play fine. When OSX is plugged into the same port, it doesn't play. I did a trace and found that vlc on OSX subscribes to the feed (IP_ADD_MEMBERSHIP) and the UDP data starts flooding in, but vlc never sees nor plays it...
