Star Wars Episode III, DVD, Bootleg, China 2005
The VOB-files are dated May 20th, 2005. (The movie premiered May 19th.) It is plausible that this DVD was mastered at that time.
You'll note that by 2005, physical copies of bootlegs such as this, were more or less supplanted by illegal downloading in the west.
This is the infamous leaked bootleg that surfaced a couple of days before Episode 3 premiered. It was reportedly sourced from an illoyal employee of one of the post-production facilities working on the film. The timecode (see below) is present the entire runtime. This proved a minor inconvenience compared to the novelty of having a near pristine source from which to dupe bootlegs. They even had authentic DD 5.1 to include on this single-layered DVD.
