To be honest, it's been so long since I've watched the GOUT I wasn't even aware there had been changes like that to the pacing at all in the SE. Excuse me if this sounds dumb, but why can't Ady just use the original GOUT/Laserdisc audio to fix that segment?

The way I understood is was that there were not enough distinct channels of audio in earlier versions. Shots have been added (of the city, as Lando speaks over the PA), and the timing of R2 getting shocked has been heavily drawn out, so the original audio wouldn't work as is.......meaning that Ady would need all the different parts in separate channels to be able to remix them in a completely new order (not original, and not SE either).
