Can you give me an sample configuration to configure multicast routing in sparse mode on a HP 3500.  I have VLAN 10 for data and VLAN 172 for Video.  I am multicasting the video on address 226.16.149.2.  I can route between the VLANs without any issue.

I don't know the exact commands for the HP 3500 but in general on each router/L3 switch you need to enable PIM globally and on each routed IP interface you want it to cross. You also have to configure via a priority setting to make one router the BSR and the RP for the multicast groups you are using.

Something like this:
 interface vlan 3107
  ip address 10.16.1.50 255.255.255.248
  no ip proxy-arp
  ip pim sparse-mode
  no shutdown  
  exit
 ip pim bsr-candidate loopback 1 priority 250
 ip pim rp-candidate 10.16.1.234 224.0.0.0 240.0.0.0 priority 150
