Here's another fullscreen transfer of the flyover shot:

That's right: In Spain, the original rental video release had the 1977 flyover.
However, this 1990 retail copy shows that later releases cut the Spanish crawl into the same PAL transfer you showed (notice the crossfade from 1977 to 1981 before the pan-down):

I wonder if even the first release just cut the foreign crawls, credits and unsubtitled Greedo scene into the existing PAL masters (as in at least some of the French and German releases).I know that on the pre-THX French and German widescreen LDs, the Greedo scene is very dark with a blue-purple cast.
Of course, none of this really has to do with HBO...:)
