Well, at least you have the appropriate hardware ?

Hve you tried streaming to multicast addresses?  That might give you
some clues....

Interesting.  But pppoe works over the device?  Try giving it a
192.168.0.x address (FYI, the marconi modem always has an IP of
192.168.0.1 which is kind of braindead for a lot of applications, but
works fine on my network here, which uses the 10.10.10.0/24 network --
But I have to set up an explicit route for 192.168.0.1 to get the
stream/

Your Internet pppoe bridge and your TV pppoe bridge are different ;)
You don't want to route though your ppp device.
AFAIK none of the Transact ISPs (or any ISPs in Canberra in fact) do
multicast, so not much use there.  Feel special because for Multicast
network things in Canberra, TransTV is about it.

Pinging multicast addresses should only work if any machines connected
to your network are accessing that address (Multicast works by having
multiple machines with the same IP address, so...).

Hope that helped some,
