I have PC (Windows XP SP3 32-bit) and notebook (Windows 7 SP1 64-bit). Both are in one LAN, both receive IP address from DHCP server, both have no preferences over other.
I'm trying to watch IPTV using udp://232.0.1.1 (from my provider).
VLC on PC starts and works fine.
Same VLC on notebook starts and does nothing.
Using Wireshark I see that on Windows XP VLC send IGMP Report request to 232.0.1.1. Then stream begins.
Notebook do not send this request - he don't send any request to this address. Of course, I receive no video.
Windows firewall is disabled. Same result on notebook for WiFi or Ethernet interface.
I've tried to enable SSDP discovery service, RIP v1 listener - when they're enabled, I see appropriate IGMP requests.
Why Wireshark don't send IGMP Report on Windows 7?!
Same result for VLC's nightly build 2.1.0 64-bit.
IGMP on Windows 7 set to version 3 (mldversion 4, mldlevel 3).
What I'm doing wrong?
