Hi, this is my scenario: I have a Sony KDL40EX503U TV and a Windows Vista x64 PC on the same network, that is, TV is on wired network to router but PC on WiFi. The TV has DLNA support so I followed instructions to share media library in the Media Player on Vista. I've turned off the firewall on the PC as well. Still the TV cannot find the PC in "Server Display Settings", but internet content (e.g. Youtube) is working fine. The router has uPNP support turned on. I'm out of ideas. Anyone with good ideas?
