Differences between it and the EOD crawl can be explained by what I said in another thread: the EOD documentary makers did their own transfers of original film elements, independent even from what Lowry was doing at the same time for the 2004 discs. There's no guarantee Lucasfilm used the EOD transfers, or even had access to them. It's very likely they took the original elements themselves and used them to do the original crawl (hence the "digging into the archives" statement on the press releases). So in the end they look a little different from the EOD crawl.
