Doing netstat -nu picked up the default group (224.0.0.56) and the port, so I 
feed that to mplayer. The good news is that it buffered something. The bad 
news is that it had no idea what it was :-( (though on one occasion it 
guessed video, displaying something that looked like a crashed C64 :-)

I assume it should be picking up something like raw DV audio?

VLC seems to understand the idea of listening to the right multicast group, 
but does nothing in practice. 

I'm all out of other player options; nothing else in Debian Etch or Ubuntu 
Feisty seems to support multicast RTP. 

(Though actually a reliable Windows client will do, as I can just use 
pulseaudio on linux boxen.)
