Ok - if you have mrouter ports being learned, then the upstream
router should be sending IGMP queries already & IGMP snooping querier
is not required.
You may want to check the igmp snooping stats & see what type of
joins etc are being seen on 1/26. Also what is the downstream switch
doing from a snooping standpoint?
Probably you should just open a case w/TAC to get to the bottom of this one.

#sh ip igmp snooping mrouter
vlan ports

IPtv router is on interface Gi1/26. This is good
On Gig 1/29 we have one of the "victim" switches without 200-202 vlans.
On peak hour more than 250Mbps of traffic flood the victim without going
out on any port. Luckily it doesn't go to the victim CPU.
