-The swearing is either replaced by an overdub, or muted. Instead of Indy telling Belloq, "Son of a bitch," the word "bitch" is gone, just implied, as is the aforementioned "God damned partner" line by Marion.
-The effects and gaffes are all consistent with a pre-2003 DVD version.
-The violence is still...uh...violent. Yes, the German Mechanice blood splatter is still present.
So, as near as I can tell with an incomplete download, the only thing different from the DVD is the swearing, the 2.0 sound, and the occasional break for commercials. Hopefully they aren;t too jarring or have too many frames cut so it can be all edited together.
It looks absolutely gorgeous, though. The film grain is present, so it has a real vintage 1981 35mm look to it, but with HD clarity if that makes any sense at all...
