The source is an International negative, all films for international release usually require a neg that is free of any subtitles so that subtitles can be added in the required language.

The Derann Super8 print uses the International master and is a straight print from it, so it is lacking *any* subtitles, so the poor viewer has to guess what Greedo might be saying.

I don't know, the Technidisc & THX LD's sources doesn't contain subtitles either, there are however clear indications that both of these sources might have contained them - Technidisc takes on a different (correct) aspect ratio at that point and switches back as soon as the scene is over and IIRC the JSC have an editing point there with a few missing frames.

This JSC-source also contains what is assumed to be the opening day Yavin X-Wing takeoff matte shot. But who knows, that matte-shot along with the other credit roll might be an international print variation but the IB Tech-prints tell us differently. I've seen that the Derann Super8 prints just like JSC does contain the "opening day" Yavin X-Wing takeoff matte shot, I assume they also have the more common credit roll found on all home video versions?
