The Sweatbox (2002)
https://www.youtube.com/watch?v=B4YzAC1d6D0 - from the Outsyder Radio YouTube channel (1 hour and 35 mins.)
Rough cut w/ time code.
The blurb (from IMDb):
“Sting’s wife Trudie Styler documents the turbulent bureaucracy both Sting and the filmmakers went through in order to complete The Emperor’s New Groove (2000), a Disney film that underwent extensive storyline changes from start to finish.”

This seems to be the same rough-cut VHS as the YouTube version above but with more complete beginning lead-in and credits outro w/ music.
