The version called “Star.Wars.Episode.III.Revenge.of.the.Sith.INTERNAL.DVDRip.XviD” has a .nfo creation date of 2005-06-04, which would be a few days before the version you have screen capped. The video framing/quality of the screencaps looks similar to the INTERNAL version which was a two .avi set. A few days later the variation : “Star.Wars.Episode.III.Revenge.of.the.Sith.INTERNAL.NTSC.DVDR” was released, and that’s my guess for the version you’ve got.
The INTERNAL variation was often identified as a DVDRip as the quality was superior to the CAMs which came out in the first month of the movies release. The official DVD didn’t come out till November, so not certain if they were starting to produce the DVDs and a copy leaked or the source of this variation was one of the digital theaters. The latter seems unlikely, but stranger things have happened.
The INTERNAL.DVDRip.XviD.nfo file explains it this way:
Quote : “We aren’t going to say where the source came from, for obvious reasons. BUT we will say this, it isn’t a TC. You can tell by the way the craft lands, the vibrations etc. It’s not a retail though, it ain’t far off.
Shouts out to Georgey boy.”
