One thing I am curious about is that when people try to restore the GOUT they never use SE footage. It seems to me that over 90% of the OT is untouched by alterations, so why not use footage from that - color-corrected of course - and just work on restoring the scenes that do differ as much as possible - rather than the whole film.

I think the best way would be to use footage from the Japanese Special Collection LD where the DVNR is worst because of the resolution differences.
