Hi,MS firewall preventing the VLC plugged TPG(my ISP provider) IPTV, I contacted to TPG they recognized it was not their problem but the FIREWALL. It was not only block IPTV from XP but also Windows 7 as well but both OS I used same IPTV before and the VLC version was not the issue.PS. I have AVG Internet Security 2011 with firewall on XP, but I switched it off in this case.Anyone could tell me how to setup the Firewall enable to make it works.Thanks,Yuan Ke1 person needs an answerI do too
