Mac OS X - Multicast UDP not working?

[Johnny Turpin]

> You can try launching VLC using Terminal.app :
> cd vlc-0.4.2
> ./vlc.app/Contents/MacOS/vlc -vvvvvvvvv --stats
> udp:@239.239.239.1:1234
>
ok, here is what the output looks like from the stream that doesn't work:

 

vlc -vvvvvvvvv --stats udp:@239.255.1.1:3001
