Ebtables oddities - inconsistancies - and overall confusion ?

Hello All,

I'm hoping someone can point me in the right direction, I've setup 
ebtables to handle multicast routing a few years ago and I believe my 
configuration is correct, however I don't appear to be seeing any 
multicast joins going out my source interface.

I have provided my current config info below, hopefully this is enough to 
explain the problem, but in short I can see the incoming packet and byte 
count increasing for my source interface, however I do not see any active 
joins go out the source interface, nor do the counters of the destination 
interface increase.

Both source and destination interfaces are patched into separate switches. 
The source interface is patched into a vlan where the multicast address of 
 239.255.45.140 is quite active. The destination interface is patched into 
separate dedicated switch with out any clients. Basically this was done to 
force the destination interface to have an active link.

When using a loopback on the destination interface it caused the data I 
was reading to flood back through the bridged source interface until 
ebtables was started and a DROP on all outbound IPV4 traffic for the 
source interface was set.

Any help in figuring out what's wrong would be greatly appreciated.

Thanks
-Alex
