Audio problem: In the sniper scene, Bond is asked if he wishes to use the soft-nosed bullets to kill the potential assassin to which he replies, 'No the steel-tipped'. There isn't any lip movement, however, after the word 'no'.
Audio problem: After the "Off to See the World" part, it shows Klaus and Claudia in the pool. The waiter tells Claudia that there's a long distance phone call for her from Europe. "Wonderful!" Claudia says, and she slides off her raft and while she makes her way out of the pool, accidentally drops water on Sophie. The dog freaks out, trying to paw the water off her and Klaus snickers at her. After the shot of snickering Klaus, it shows Sophie turning her head towards Claudia and you could hear her bark. However, she does not move her mouth as if she's barking and the barking noise sounds quite perky.
Audio problem: The keyboard Kevin gets from the music shop seems to have an interesting trait, in that the high notes are on the left. This must either be bad "audio dubbing" or something to do with the shot perhaps being reversed, although I doubt this. It's most likely a post-production audio error as very very few keyboards or pianos are configured in this way.
Audio problem: The radar operator (making the sounds of a garbled intercom) is laughing through his next line "I'm having trouble with the radar, Sir." (After/when Dark Helmet throws the intercom across the control panel). (00:21:45)

Audio problem: When trying to steel the BET, Serpentor fllies in close and Duke grabs onto his glider. The sounds of TIE Fighters are used for Serpentor's glider. You can even hear Darth Vader breathing for a moment. (00:15:45)
Audio problem: As Neil is talking to his coworker about getting on a plane, the audio is either different or synced wrong, as the coworker says something different. In the shot facing Neil his mouth doesn't match.
