->Sorry, but it's ambigous to me, which firmware you mean "this" time? It is already fixed in this latest one ,or it will just be in the upcoming firmware that you have been forecasted?
I have modified my post to read "Firmware 1.0.5 will improve things for people experiencing stutter because of incorrect out refresh rate but not if you are seeing stutter when refresh rate matches video.".
The 'microstutter' problem is something experienced by only a few people and not in a consistent way. It has been hard to nail down a cause. However, despite this HiMedia said last week that they have identified the problem and it will be fixed entirely in future firmware. Not 1.0.5, the next firmware.
It's important to make clear that playback of all files for most users will be silky smooth already with 1.0.5.
