What kind of ethernet card do you have?  Does it have the MULTICAST flag set 
in ifconfig?

There are a few bugs in /sys/netinet/igmp.c which have been fixed in -current; 
if you want to be a multicast client you should be able to just get igmp.c 
from -current and rebuild your kernel.  I think there is still a tunnel bug in 
the 0322 snapshot; are you doing routing between multiple interfaces or are 
you using a tunnel?
