Hi Harmy
I found the films on a torrent search website. They are described as follows (Empire and Jedi are similar):

Star Wars: Despecialized Edition.
All credit goes to Harmy http://originaltrilogy.com/forum/topic.cfm/Harmys-STAR-WARS-Despecialized-Edition-HD-AVCHD-DVD9-and-NTSC-DVD5-AVAILABLE-see-1st-post/topic/12713/ Star Wars in HD without the bullshit tampering George Lucas did to the DVD and Bluray release.
Edited. Sorry.
