It's driving me mad. Sometimes it also gives an error message about a firewall might be blocking it but this is random and sporadic when it reports this.
EDIT
I've now found I can play music through the media server if I allow it a long time to build the playlist of music (5000+ songs), I still get the connection error but it seems to go through ok. However the video section still gives me the connection error.
I can also do the same with pictures. It claims it can't connect but when I force it to do a slide show from my PC it works
It's also weird because if I connect to my Vista PC as the video/pictures source I only see my "users/me/downloads" or "users/public/pictures" folders with one folder inside it. Although on my PC I see everything through MP 11 just fine videos/pics/music all through the same NAS drive. So the media server is working, just not properly with my xbox.
help!!!
