For what it's worth: I was at my local Fry's the other day, and they were
showing off their various HD panels by playing "I, Robot" in high def.
In the particular (action) scene that was playing when I walked by, I
noticed quite severe compression artifacts (blocking). The picture was
otherwise superb, it's just that in scenes with fast motion, blocking
was quite apparent.
