Just stumbled on this thread. I think this makes it the 3rd talking about the VC-1 problem, but the activity seems to be here rather than where I was contributing.
Just wanted to report that I’ve tested a fixed 60Hz refresh-rate on all of the titles I listed there. Definite improvement.
There is the slight judder in panning scenes that you expect from an incorrect refresh rate (I was originally delighted with the improvement you get from auto switch refresh rate - well worth the momentary delay when the TV switches mode) but none of the horror I’d seen otherwise.
I’ve tested the update issued above, but no dice I’m afraid.
