Human Error - S7-E18
Audio problem: When Chakotay comes into Seven's quarters at some stage, the comm badge sound is used, not the standard door chime sound.
The Plague - S2-E6
Audio problem: When Bishop Brennan calls for the first time at the start of the episode, Ted panics and pretends to be French before hanging up the phone. You can still hear Bishop Brennan talking on the other end of the line for a few moments after Ted hangs up, which obviously shouldn't be possible.
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: 2nd January 2004 - Cameron shouted "Don't you want a lift?" out of the car when his friends ran away (thinking it was a killer that had stolen the car.) His lips moved when he spoke, but it was obviously a dub as the words didn't match.
Audio problem: When Rembrandt is walking down his steps to his car while singing the national anthem, the words don't match what his lips are doing.
Audio problem: When Xena says "It seems so haphazard" the word haphazard is said with her Kiwi accent. (00:29:30)
Audio problem: When Gunny's sister shows up at JAG, Gunny's mouth doesn't move when he greets her. (00:08:45)
Audio problem: When Brian escapes his room and the headmaster with security is checking the rooms, if you look very carefully while the camera is going to Brian's room, you can see the headmaster hitting the door with his hand out, but the sound sounds like it would if he were hitting it with his fist.
Audio problem: The scene where Tom goes to his home, to be confronted by his wife, the dog, and another man holding a shotgun. The other man has just told Tom that either he walks away or he gets shot in the leg. There is then the sound of the dog growling for several seconds, but the dog's mouth/muzzle isn't moving, and it isn't growling.
