Just to close the loop on this, there is certainly an error here, and it's like that on the GOUT, which means it likely has been an error on most Castilian dubs of the OT since it was first out on home video. IIRC there's a reel change right in the middle of the trash compactor scene, so if, perhaps, there was damage on their Castilian audio at the end of one reel, maybe some wise guy thought they could just splice in the Latino audio and nobody would care. When they went back and re-did things for the Special Editions, they either found some undamaged audio or managed to repair or re-record it, so it's correct on the Blu-rays. Since that scene isn't very much altered, it should be a piece of cake to restore.
It reminds me very much of what happened with the missing dialogue on the German dub, and I wonder if the other pre-home-video dubs (French, Italian) may need some looking over too. RobotWalrus has checked the rest of the trilogy and the Castilian dubs for those are fine.
I'll make a fixed track and make it available to any interested parties. I don't have it yet, but let me know if you're interested.
I wouldn't be too surprised about the wise guy part, since these kinds of mishaps are not unheard of in my country. I own myself a copy of the Castillian DVD of the 20th Anniversary edition of The Name of the Rose, which restored a couple of scenes that were deleted from the theatrical release, and instead of re-casting the original Spanish voice actors (or just leave the new scenes in English and adding subtitles if they so needed to be cheap about it), they filled in the blanks with audio parts performed by obviously amateur actors whose voices sounded nothing like the originals (the butchery begins at about 0:47).
Also, for puritism's sake (which I failed to mention in our PM exchanges), I compared the audio in the Special Edition of the film with my (circa 1986) VHS copy of the original, unaltered film. The Castillian audio for the trash compactor scene is exactly the same in both copies, no dialogues were re-recorded for the Special Edition. :)
Needless to say, I'm definitely interested in obtaining the fixed audio track. :3
