Real Problem with IPTV in Windows 7

[Jimbo77]

Good day.
At the first i'll say: in winXP all worked fine, within about 2 years.
I upgraded to W7. Clean install. Windows_7_EN_x64.
IPTV, with the about 70 channels, doesn't work. No error messages appears.
When i start VLC and tell it to play some channel it could (often just nothing happens) do it, but, after 1-2 minutes it just stopped. Just stoped and... it's all i can say.
When video playing it's possible to switch between the channels, but some of them are really pixelated(in winXP all was fine).
Another amazing thing - even those one or two minutes of video VLC can only play when windows firewall is ON O_o!!! (of course all rules are fine)
No matter what i was trying to do, i could not get IPTV even 1 second playing with WFirewall service stopped.
When video flow stop it can play again after 2 hours or after 1 minute, but almost always it's dead forever. Closing, reopening, reinstalling VLS has no sence here.
I think it's even all around Windows 7 kind of trouble(something with the IGMP, multicast maybe??). But how to recognize and fix it?... Have you any things people?

Open Tools -> Messages... (set Verbosity to 2) before opening the IPTV stream.

[VLC_help]

I can't see the problem in the log. Have you tried to spy with Wireshark?

[Jimbo77]

Have you tried to spy with Wireshark?

I'll try it. But i don't guess this is the network trouble around. In the same machine/network all was really fine in WXP until W7 has been installed. The problem, i think, most likely the Windows 7 problem itself. If you'll search across the inet you can find the questions similar with my. But what it really is?...
Really sad

[Jimbo77]

This is what wireshark tells, just after VLC starts:

As always no video present.

P.S. Few times VLC began play a video with the WFirewall service turned off, therefore, i think, the problem is not in firewall at all(as it could seems in the first post).

[Jimbo77]

Another info:
I tried just to leave VLC with the run channel for a while, and... after about 20 minutes of idle it has played
It is something like a video flow is coming to VLC, from wire, very slow
