I have a different problem with this update:
I can no longer view Amazon Prime videos on the full screen. Now I have 4 large black bars and the image in the centre. The old series like Married with Children or The Shield can no longer be viewed in full-screen mode.
Please tell me you are looking into this!
It works on my other TV that has the old update.
This is happening on all 4:3 content on Amazon Prime for me, too. Instead of black bars on either side like it used to (and like every HD TV since the invention of it), it puts the image into a 16:9 rectangle in the middle of the screen, with large black borders all around. The entire image is squashed vertically because it's the wrong aspect ratio. HD stuff plays and looks just fine. It started immediately when I did the software update, so there's no question it's due to that.
