Here's a quick and dirty comparison between the BD (should be same encode as the HD) and the Sky HD broadcast.
If you look closely, the broadcast has a very fine layer of grain over the image. The woman's cheek, the car door, the tree line, the general's face/neck, the solider in the background... not there on the BD encode.
(Yes, I can see that the BD has better detail on the general's right shoulder - bear in mind this is
a broadcast, it's not perfect, but pretty damn good.)
This one should be much more obvious. Again the general's face, the other solider, their clothing. Fine grain on the broadcast, none on the BD.
While you could dismiss this and just say "oh, well the New Line HD/BD still looks pretty damn good", the French HD DVD has the same detail *and* the grain. Why can't the New Line offering do that? I don't have the French version on hand, will have to wait till after the holidays before I can add those screens. But I've watched that a few times, the broadcast a few times, and I've seen the movie digitally (2k DLP), and that had grain too. When I started watching the New Line disc, I knew something was immediately amiss. It's much more obvious and disheartening in motion.
EDIT: Whoops, I meant "Captain". As many times as I've seen it, I forgot that
