I agree with all the comments on camera shake in Ultimatum. Paul Greengrass needs to look into a Steadicam
I second Murphs's take on the Children of Men soundtrack on HD DVD. It's "only" DD+ and it is definitely one of the better sounding discs I own. Bitrate hounds complaining about lossy audio tracks on some hi-def discs can just stop and insert foot in mouth as they hear the experience of this disc.
