Power Connect 6224 IGMP Problem

Dear Folks,

I face a igmp group membership lost issue for a while and I check my logs. it seems there is a problem at multicast table entries. Can Anyone help me about that issue? Last firmwares has not any improvements about igmp. My topology is "SW(igmp snooping enable)----> (Vid 20,21,22,23) dell 6224 (Multicast router) ----->DVBtoIP streamers (at Vlan 19)"

!Current Configuration:
!System Description "PowerConnect 6224, 3.3.7.2, VxWorks 6.5"
