I have four tvs, two x Panasonic G20 2010 models and 2 x Samsung LED smart tvs 2011 models. I have a Buffalo NAS 4TB media server, I run Plex media server on my PC and I have media streaming turned on my windows 7 PC. 3 out of 4 of my TVs can see the 3 x media servers; However one of my Panasonic G20 tvs cannot see the Media servers. I have checked and the G20 has internet access and I have tried another lan cable, I have also tried to reboot and software update. I wonder if its because I have 2 x G20s on the same network? I am stuck and would be grateful for any advice?
