Not really sure but I would think that even with or without IGMP/PIM enabled on the interface, the router probably doesn't know what to do with that packet since it doesn't have corresponding IGMP/PIM join state to match the incoming packet. Therefore any packets sourced from a multicast mac address are probably pitched in the bit bucket. at least that seems to make sense since you've indicated that static arp entries are working...
