Serviio

hi im having troubles detecting movies to my PC, but i can see movies using my TV

GUI detects the PC but upon looking at VLC or WMP, i cannot see my movie libraries.

Can you help me how to troubleshoot? thanks

WMP is not a DLNA client so will not work.
VLC - look under View, Playlists, Local Network, Universal Plug'n'Play - Serviio should be there. Click on it and wait - it can take a while before folders/categories show up.

serviio runs on a ubuntu server and i configure it using seviio web/ajax gui,

my pc with VLC is locally connected to my serviio server and my ipTV's
i still dont see serviio in VLC upnp. its just blank.

what any other troubleshooting do i have to perform?

Firewall on our PC would be my guess. Disable firewall and see if it comes up.

firewall is already disabled sir, but its still not showing in my VLC upnp list

Have you waited a long time? Server discovery in VLC can be very slow - see viewtopic.php?f=5&t=5620. I would have expected you to see the Serviio icon though, its normally the folder discovery that is slow.
It may pay to install another DLNA capable client - this will let you know if its a network issue or specific to VLC. XMBC is one.
