The Campout - S2-E5
Audio problem: When Laura and Nellie are on the branch going down the rapids they can be heard talking, but their mouths either don't match with what they are saying or don't move at all.
Tall Woman in Red Wagon - S1-E6
Audio problem: When Rockford is having his no dill lunch with Sandra Turkel, the audio, in particular at the beginning of the scene, changes ambience noticeably when the camera angle changes - not quite justified, they are sitting at the same cafe table. (00:05:20)
