"This is a 1080p HD version of the original theatrical edition with appropriate scenes upconverted from the DVD. No attempt was made to clean up or enhance either source in any way."

Do I take this as meaning he just grabbed the HD SE files, and then edited in pure GOUT scenes as-is? Because if that's true, I don't think it would really be watchable. He said about 5 minutes are from the GOUT for ROTJ, so I guess he put the whole scenes in instead of shot-by-shot. This was probably for the best since the back-and-forth quality change will not be so disorientating, but it still will be so distracting that I'm not sure what the point of watching it in HD is, especially with the screwed up colouring (which obviously will not match).
