EDIT: Oh, gosh, I'm really not sure how this happened, but it appears I've inadvertently included and translated the audio commentary track which was recorded for this episode and included on the show's Blu-ray release. See, when I used MakeMKV to extract all the "titles" from the disc, it seems the first video file presented (and extracted) which matches this episode is actually the one with the audio commentary. The regular episode audio was on a later video file, which I failed to notice. I did think it was strange that the audio I remembered seemed quieter and there was more dialogue which was louder than it, but I thought they just made some changes to the episode for the TV version.
Really sorry for any confusion!
