I've been having freezing problems this afternoon/evening... this morning it was working fine. I am running a continuous -t ping on 66.iptv66.tv (my server using a Mag254) and when the tv freezes for 5 seconds the pings do not drop at all, so it's not an ISP problem, if it was the pings would miss as well. I tried VOD and same problem there, I can normally watch a movie no problema.
It may be that the peeps not having problems are not on IPTV66 as there are 3 different servers/ip's. Just my 2 cents.
