A little trick I use to make sure I am getting the multicast on the right interface.
- Open cmd as administrator (right click run as administrator)
- Delete the default multicast routes. > route delete 220.127.116.11 mask 240.0.0.0
- Add the route to the NIC you want. >route add 18.104.22.168 mask 240.0.0.0 <IP of NIC>
You could always get more fancy if you had different multicast feeds on different networks but mine all live on one.
