[AG-TECH] Weird Network Thing

[Michael Daw]

We're experiencing a weird problem. Audio in the University of Manchester
Virtual Venue is very lossy - sometimes non-existent. When we switch venues,
the problem goes away.

E.g. Pittsburgh can send and receive video but doesn't show up in rat at all
in the Manchester VV. If we switch to Pittsburgh VV, then everything's fine.

I don't understand what can cause this - surely they're just mcast
addresses, yeah?

Can anyone shed any light?

--Mike
