I'm evaluating Mezzmo at this moment to stream media to my LG 32LE5510 TV.
Installed on a XP machine, everyting works well.
Installed on a SBS 2008 server with the same settings, i can browse the media, but when trying to play the connection drops.
I really would like to have it working from the SBS 2008, because it's the only machine which is always on.
