Saw one avov log on but not play any channels. After resetting modem, router and avov, found that the port on router had gone bad. Changed port and channels played.
I have the same issue with my AVOV. Channel # 600 and above would load. The English channels would not but channel listing / EPG shows up. I have tried all the tricks I could but up to now, same issue. It started after the firmware upgrade last month.
I don't think that it's a networking issue because the box works in specific range of channels (600+) but not on the English channels. Obviously, the box is connecting to the server. It would be either connecting to the server or not. There's no such thing as partially connected so it would get partial channels.
