I can view only images on Win XP

Hello to all,
I have a Panasonic Viera Smart TV. I want to read the video on a PC with Windows XP installed. Unfortunately I can only see images on television and no video, even if they are in the same shared folder. What could be the problem?
Many thanks to all.
Bye.
