Mark -
I personally doubt it. But I made that most misunderstood comment to
Craig in a discussion of blue laser DVD using advanced codecs. I was
actually thinking of something like 4:4:4 AVC or VC1 at 25-30 mbps which
could hopefully do it quite well, especially for 24fps movies. (If those
are even going to support 4:4:4 encoding).
