I can make MVR work on 1 switch but not two.
Can someone have a look please?

TROUBLESHOOTING
1) !r5 is connected to the correct port
r5#sh cdp nei
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater
Device ID Local Intrfce Holdtme Capability Platform Port ID
sw2 Fas 0/1 147 S I WS-C3550-2Fas 0/5
2) Switch 2 is trunking properly
sw2#sh int trunk
Port Mode Encapsulation Status Native vlan
Fa0/13 auto 802.1q trunking 1
Port Vlans allowed on trunk
Fa0/13 1-4094
Port Vlans allowed and active in management domain
Fa0/13 1,4-5,342
Port Vlans in spanning tree forwarding state and not pruned
Fa0/13 1,4-5,342
3) MVR is configured poperly
sw2#sh mvr
MVR Running: TRUE
MVR multicast VLAN: 4
MVR Max Multicast Groups: 256
MVR Current multicast groups: 1
MVR Global query response time: 5 (tenths of sec)
MVR Mode: dynamic
sw2#sh mvr interface
Port Type Status Immediate Leave

Fa0/5 RECEIVER ACTIVE/UP DISABLED
