Routed IPTV

Hello everybody, I recently bought a new ERPoe‑5 and try to get working with my ISP. The router will be used for normal internet traffic and IPTV.

Configuration:

eth0 internet

eth0.4 VLAN 4 for IPTV

eth1 Dune IPTV box

eth2 switch for the rest of the devices

I read all the posts about IPTV and I got it almost working except for the fact that my tv doesn't have any sound and vision. IGMP-proxy seems to be working based on the multicast stats. At this point I have no clue with I'm missing in the configuration. Any help is welcome.
