I've had a look and it's definitely HD, just not a great source. Soft for the most part but natural at least. Not as scratchy as I was expecting so I don't know if Pinewood did more to it than Walter because haven't seen his. The vertical lines are there but quite feint. Again, I don't know if they're the same as the Scorpion or with additional clean-up. Overall, becasue of it's softness and if the cleanup work is the same, it's probably not a massive difference from the Scorpion DVD other than the compression will be better because I don't see any problems with that. Big upgrade from the Odeon DVD though.
Here's an absolute rubbish camera shot. The vertical lines are there, you can vaguely see them on her forehead but they're not particulalrly distracting to me. I can imagine projected they would be more though.
