I'd like to point out, though, a little problem I found in the Castillian Spanish audio track. From 1:16:45 to 1:19:46 (the first half of the trash compactor scene), the audio is in Latino Spanish instead of Castillian Spanish.

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.
