Oh, and I misread your initial post – the 2.5 Castilian track has a DIFFERENT problem which was fixed in 2.7 (Latino dialogue mixed in the trash compactor sequence). People have been complaining about that for ages, so I thought you were too.
This other dialogue problem sounds very different – it sounds like the THX Laserdisc and GOUT tracks contained either some badly-mixed audio or mispronunciations? Did any release prior to the GOUT contain the other pronunciations (early Laserdisc, VHS)? Just wondering if they re-recorded the lines for the Blu-ray. The Blu-ray isn’t usually a very good audio source because it doesn’t mix well with tracks from other sources, so if there’s a “good” recording from earlier, that would be best.
