I have a Sony BDP-S480 and a Yamaha RX-V671. I've installed Mezzmo to try it out.
All the Windows Firewall settings look right, and I added a Folder of video files on my PC.
I can see the Mezzmo server from either of my devices (I have previously used TVersity). However if I go into Videos .. All Video Files I get ""No Valid Media files found" or similar.
On the Mezzmo server in Media devices there are no devices shown. I've tried the "IP address only" option, rebooted the PC, router and devices, and now I'm stuck.
Any other suggestions of things to try?
