Decided to take the TV back to the store and get my money back. The new firmware makes it almost unusable in certain cases.
The HDNM is broken.
The backlight dimming feature is broken.
The menus are slow (and broken at times as well as there are instances when the icons are completely messed up).
The tv loses connection to hdmi devices.
There's a crackling noise when the tv outputs dolby digital sound.
The settings reset to defaults for no apparent reason.
And that's on top of a large number of smaller irritating problems.

I have to say that this TV is a huge disappointment, especially considering the price.
