Thanks much for creating this thread! I bought my SV422XVT about two weeks ago (from Sam's Club online) and still have this version firmware:
From what I've read, it sounds like I should be expecting my tv to automatically download the update either by shutting itself off & restarting on its own, or overnight while the tv is off.
I had no issues setting it up and currently have wireless (and have no issues with the wireless on my wii or laptop). I have unplugged the tv and back in again, and the next day, still no firmware update. I have watched movies using the Netflix app, and also use the Yahoo weather app with no problems.
I am impatiently waiting for USB functionality, Facebook, Pandora, and eventually, according to a Vizio phone Tech guy, Yahoo Email. (I know, that one is a long way off yet...)
Anyway, is there anything more I can do?
I love this tv and can't wait to get full functionality from it!
