multicast on cisco 3750 and cisco rv180 - only receiving unicast

I've been struggling with multicast for some bit now.  I receive video through unicast.

The following is true:

A WS-C3750X-24P-S  is configured as such:
interface GigabitEthernet1/0/11
 description Uplink to CiscoRV180
 no switchport
 ip flow ingress
 ip flow egress
 ip address 172.27.255.33 255.255.255.252
 ip pim sparse-mode
 ip igmp query-interval 125
 flowcontrol receive desired
 spanning-tree portfast disable
 spanning-tree bpdufilter disable
 spanning-tree bpduguard disable
end

ip pim rp-address 10.10.254.32
no ip pim dm-fallback
ip mroute 172.27.91.192 255.255.255.240 172.27.255.23
ip route 172.27.91.192 255.255.255.240 GigabitEthernet1/0/11 172.27.255.34

router eigrp 64512
 network 172.27.90.0 0.0.0.127
 network 172.27.90.128 0.0.0.63
 network 172.27.90.192 0.0.0.63
 network 172.27.91.0 0.0.0.127
 network 172.27.91.192 0.0.0.15
 network 172.27.255.20 0.0.0.3
 redistribute connected
 redistribute static
 passive-interface default
 no passive-interface TenGigabitEthernet1/1/1
 eigrp router-id 172.27.90.1
 nsf

connected to WAN port on the RV180 switch:

WAN Information-
IP Address: 172.27.255.34
Subnet Mask: 255.255.255.252
Gateway: 172.27.255.33

Routing Mode: Gateway (NAT)

Access Rules:
Default Outbound: Allow

One-to-One NAT

Allowed Networks: 192.168.2.151 - 154 Length - 32

I can see the video in unicast but can't see it in multicast.  Do I have the routes right? 

multicast debug is on. I see no traffic concerning 172.27.91.x.

None of the WS-C3750X-24P-L  solutions worked.  Had to take Router out of the mix for broadcast to work.
