ASUS RT-N66U IPTV connected to LAN port + udpxy

[fess]

Hello!
I have 2 ethernet-cable from my povider. One with internet (I connected it to WAN port on router) and other - with IPTV (I connected it to LAN4 port).
I can watch IpTv on PC with VLC-player using udp-links (like udp://@233.26.198.130:5000). But I cannot setup udpxy to watch iptv via udpxy. How can I setup udpxy to work with this configuration?

I can not understand where I am wrong .
There is all data that I collected.

Short description:
robocfg - there describes the current Vlan and ports:
Port 0 - WAN;
Port 3 - Lan-port that connects to the PC in LAN;
Port 4 ( Vlan3) - Lan-port ,With IPTV provide;
Port 8 - CPU-port - all router programs are executed there;
vlan1 - vlan for all lan ports;
vlan2 - vlan for WAN.

Ifconfig: br1 - bridge to vlan3, IP - address is assigned manually but it could be any.
After this setup, if I execute udpxy -p 4000 -m br1
and listen through tcpdump vlan3, I will see udp-stream (tcpdump-log is attached). As I understand that udpxy correctly subscribes to multicast and begins data transfer, but I see nothing in the player (VlC-player).

Iptables - not touched, to be exact - tried, but there was no sense.
iptables_dump - it can be downloaded from the web interface of the router, as I understand it, the udp with IPTV goes by this rule : Chain PREROUTING (policy ACCEPT 7214 packets, 8292K bytes)
but what's happen next with udp - is unclear.

Maybe someone has any idea ?
