Audio problem: While Maria is singing "God Rest Ye Merry Gentlemen" accompanied by Mary Bennett, the movement of her lips is out of synch with the audio track.
Audio problem: When Lizzy, her aunt and uncle are in the tavern dining room discussing whether or not they should visit Pemberley, pay very close attention when Lizzy says, "We've no business there." The pitch and tone of the voice sounds completely different than Jennifer Ehle's. It sounds like it was dubbed.
