Sony kdl-40nx710 not recognize videos Serviio on Lubuntu

I have a problem. I installed Serviio 1.4.1.2 on a laptop with Lubuntu 14.04 lts and my tv is Sony kdl-40nx710 .. because the tv recognizes and plays music and photos yet Videos folders are empty. Ie not recognize the videos within them.
Anyone know why this happens?
thank you very much

I'm not a linux user, but I think problem comes from ubuntu settings, probably access right on shared folders...
