It seems Vizio is trying to fix their long standing 24 fps 3:2 pull down issues with film media. I'm guessing its only affecting those that aren't using Smooth Motion which inherently masks the issue. It looks like the firmware update issue is worse on the older XVT models like the 552 & 553 which probably have more outdated electronic components.
OK, that explains it, I have Smooth Motion turned on all the time and I've been turning my settings to off to see if anything changes with this screen flickering. When SM was turned off I did notice that the movie didn't seem smooth (slightly jerky) but I thought it was because I was so use to SM on.
I have the same FW you have.
I guess I'm going to call for service in this flickering and the problem I have when there are thin horizontal lines on the screen that jump up and down. The beginning scene of Hugo really showed it, the lights from the city were flickering like crazy. Doesn't happen on my 553.
