This is the best looking HD-DVD I've seen yet. It's not quite "flawless" as suggested by HD Digest's review but it's close. In the narrated, stille shots in the film's opening minute I saw a couple of lines wiggle. After that, I was just stunned by the video quality and could not find a bloody think to whine about. In the scene where Jeff Bridges has spent all night at the hospital....now it's morning and light is pouring through a window....the camera moves up close to Bridges, you can see bits of dust in the air. I can't recall ever seeing someting so small as dust in the air in a home video. That shot just amazed me.
Apollo 13 has a lot of film grain showing, which is of course intentional but is easily mistaken for poor pq, hence it's not the best demo of HD-DVD's capabilities. Seabiscuit is the opposite, almost totally grain free and thus a great demo disc. It's the best looking of all the HD-DVDs I've owned or rented, though Training Day comes very close.
Don't forget Chronicles of Riddick! Some people didn't really like it substance wise, but visually, it was stunning. I found how HD made the CG look so realistic to be the best eye-candy from COR.
