I think your setup looks ok.

I suppose you have IGMP enabled under pimd on pc2's interface attached to pc1,
right? Then "show ip igmp sources" on pc2 should display the
192.168.1.12 source.

Are you sure the receiver application is issuing a correct IGMPv3 join
to (S,G)=(192.168.1.12,232.2.4.5) ? You can use tcpdump to verify the
ICMP join.

I run nepim to test IGMPv3 joins, it looks like this (on pc1): nepim
-j 192.168.1.12+232.2.4.5
To get nepim: http://www.nongnu.org/nepim/
