The Sponge - S7-E9
Audio problem: When Kramer says "I read it in Wall Street Week," his mouth does not sync with the words. It looks like he said "Wall Street Journal."
Misadventure of Mighty Plumber - S1-E12
Audio problem: When Mighty Plumber is unlocking the door to the treasury, the sound of it being unlocked can be heard before it is actually unlocked. In the same shot, Mighty Plumber has a wrench, but in the next shot, it disappears. (00:09:00)
Audio problem: When Jerry goes over to open the jail cell door, the sound effect of jingling keys can be heard, however the actor isn't holding any keys. The jail cell door doesn't even have a keyhole.
Suggested correction: When the Sergeant tells Jerry to open the cell (00:18:20), Jerry reaches to his left side to retrieve keys from his duty belt (there is no "sound effect of jingling keys"). And keys were visible dangling from Jerry's duty belt when he told Philip to calm his wife (00:17:10). Secondly, the jail cell door does indeed have an old-style keyhole (00:18:30).
Dreams, Schemes and Putting Greens - S1-E4
Audio problem: When Maurice exhales at the end of his sentence as he protests the Japanese businessmen walking out of his house, the sound of his exhale is spliced off mid-way through. (00:38:55)
