Audio problem: Around 3 and a half minutes into the episode, Doug, as the Chameleon, says he has a good idea as to who would've taken BeeBe's radio. The end of this sentence is very unnaturally pitched up.
Arthur, the Invisible Bear - S2-E4

Audio problem: When speaking about the hidden beauty parlor in the submarine Velma's voice comes from Daphne's mouth briefly.
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).
Audio problem: During the opening credits no one moves their mouth when they notice Superman and say "it's a bird...it's a plane..."
Audio problem: In the final song, "This is What It's Like to Be Lovers", the lead male studio singer starts the song, not David Cassidy, then they switch to David Cassidy's real voice halfway through for just two lines, then they switch back to the male voice of the studio singer.
