Just got my Samsung TV, connected to the network WiFi.
Got the PS3 Media Server installed on my OSX, with a little bit tweak:
PS3 Media Server\renderers\Samsung.conf:
MimeTypesChanges=audio/wav=audio/L16|video/x-matroska=video/avi
StreamExtensions=mkv,mp3,mp4,avi
The movies are streamed awesomely to the TV!
