Someone on another thread said Vizio will send you a flash drive with updated firmware, which will supposedly load if you plug it into the otherwise nonfunctional slots. I'm STILL wondering if there's a way to hack this thing- I've searched and found nothing, not even any service-mode codes.
I got today's update- sadly the smart-dimming problem STILL exists, where the LEDs go completely out when there's any fading to black. If you keep Brightness at 71 or higher it doesn't do it- it should be turned down lower than that, but still looks better than with smart dimming turned off.
They did however FINALLY fix the Netflix sound problem so you actually get stereo now, and Vudu is outputting Dolby 5.1. Amazon is still just doing 2-channel PCM however. The "Video On Demand" thing finally got updated to access some web videos, Yahoo Video is back and there's a new app that lets you listen to what seems like every internet radio station out there, which is pretty cool. Would almost leave it playing while I sleep tonight, but it's been on all day and probably needs a break.
I'm going to find out who to write about the smart-dimming thing- I thought they were aware of it already.
