IGMP snooping not working

Hello, i’m running the following network:

MumuDVB ----------------------------- Mikrotik RB751 ------------------------ PC with VLC

MumuDVB ip address: 10.0.0.201
PC ip address: 10.0.0.98
MumuDVB is connected in port 2 of mikrotik, while PC is connected in port 3.

MumuDVB is generating 10 videos with the following multicast addresses:
239.100.22.0
239.100.22.1
239.100.22.2
239.100.22.3
239.100.22.4
239.100.24.0
239.100.24.1
239.100.24.2
239.100.24.3
239.100.24.4

I want to avoid the flood of those traffic in to the PC, i want to have only the traffic of ONE video when VLC request it, but i have enabled IGMP snooping and still is flooding everywhere those videos. I don’t know why, and if i disable “unknow multicast flow” then my PC can’t connect to those multicast address, what am i doing wrong?
