Adywan has done more work than just SW:R. His AVCHD releases are not fan edits, but actual HD versions of the 04 SE. As Ash was explaining, ANH and ESB have been color corrected, ANH has had Jabba removed and Greedo shooting first, in an attempt to make it closer to the originals, but other than that, it is the SE. ESB has been modified to be closer to the 1997 SE. ROTJ is the unchanged DVD version, but from the HD broadcast.

So all changes made to these have been in the interest of restoring them to previous official versions of the films. Absolutely nothing like SW:R, which is a fanedit.
