TVs remember and display servers that they have connected to in the past. So unless the server
named "puppypc:root" happened to still be running it would not connect.
The server you are looking for on the TV will be named "ETPs DLNA Server".
Explore some more menus on the TV it should pop up on one of them possibly
with any trailers on Sony Playstation. Another possibility is that you have a
filter engaged on the TV which is only allowing jpegs or audio to be seen rather than video.
Definitely NOT.Does the content need to be shared using Samba?
