I was on right way, the problem was that my routers did not know path to source of multicast
(ip was out of my network) I've discovered that problem solved when I do smth. like

interface Vlan151
  description digitaltv
  ip address 10.0.0.5 255.255.255.252 secondary
  ip address 218.19.182.225 255.255.255.252
  ip pim sparse-mode
end

or

interface Vlan151
  description digitaltv
  ip address 218.19.182.225 255.255.255.252
  ip pim sparse-mode
end

ip route 10.0.0.5 255.255.255.255 218.19.182.226


What method is better?
