heres the problem. These brand new DVDs will be using ancient video masters. Jim Ward, of Lucasfilms, comments: "The original films' video quality will not match up to that of the restored versions. 'It is state of the art, as of 1993, and that's not as good as state of the art 2006,' Ward says." That quote can be found in this article from USA Today.

Some of the worst official dvd releases out there for movies have simply been laser masters dumped onto dvd with no care involved. And that's exactly what we'll be getting from the company that at one time was at the forefront of producing quality presentations.

It seems as if this release is ... and I had had a sad suspicion of this ... intended to make the 2004 releases look better by comparison.
Oh well. Color correct the 2004 version and edit the shots from this into it, and you'll be fine.
