Hey man, any success? I'm using 48w600b as well, no luck to have Netflix app so far. I have already changed the DNS and can actually access and register for an account on Netflix using the TV's web browser. So it is not an issue of DNS anymore, however I still cannot make the Netflix app appear. Help.

Bro, I managed to get Netflix working!! I am not sure what I did right. I mean I did change the DNS address but it didn't appear immediately after that. After 1 day only did the app appear with a few other apps not previously seen like Hulu Plus etc.I guess the tv updated itself after changing the DNS address.
