The One With The Routine - S6-E10
Audio problem: When Ross has finished telling everyone the story of the dreidel, we cut to Monica and Chandler's reaction shot which shows Ross' mouth moving even though he is not talking. (00:01:30)
Dibley Live - S2-E2
Audio problem: During the scene where Jim and Owen are trying to bribe the Vicar with chocolates, just after they take them back, you can hear a mysterious voice say "chocolates". The only person who this sounds like is Jim, but in the next shot, his lips aren't moving.
Ground Zero - S4-E6
Audio problem: When Greene is outside by the river explaining what happened to him, there are a couple of really bad sound edits in the background noise. These are really obvious as the sound suddenly changes, and for some reason the background noise in this scene is very loud, almost as loud as the dialogue; very strange.
Prey of the Black Panther - S2-E7
Audio problem: When Black Panther is saying "The Black Panther's ready to stalk again," he doesn't press his lips together when saying "Panther" in order to produce the "P" sound. (00:21:12)
The Accident - S1-E1
Audio problem: After school when Alex and Ray are walking the camera is far away but you can see that the sound of the person that is talking is different than who is seen talking.

Six Forgotten Warriors Chapter 4: The Six Fight Again - S5-E5
Audio problem: When Dr. Groitzig is saying "It's been so many years," he has his fingers in his mouth. While it's possible to speak with fingers in your mouth, your voice will sound quite different when doing so, and Groitzig's voice sounds normal.
Origin of Iron Man: Part 1 - S1-E11
Audio problem: When Fin Fang Foom is saying "I'll do nothing for you, until you agree to do something for me," his mouth is hardly moving for any of the words. (00:04:05)
Audio problem: In the last scene of the episode Sheridan says to Mr. Sebastian "The morning after the last of a string of murders in the East End." His lips however, say West End instead of East End. The script and initial broadcast used the words East End, but after it was pointed out that this was factually incorrect, the line was dubbed over for all subsequent broadcasts and releases.
