Thanks for posting that, Tom. It's a little dry technically (understandably so) but a great look at some more of the challenges they faced with this project.
Personally I prefer this kind of informational presentation, and enjoyed it better than the remastering doc from the bluray.
It's amazing after reading about the state-of-the-art fx back in the 90s how they talk about the technology from that time as if it were the dark ages.
They've come a long way.
