Audio problem: Just after Bond disarms the bomb at the circus, Octopussy asks Magda, "Where was Kahn heading?" Magda replies, "Back to India," but her mouth movements are "India, of course."
Audio problem: When the circus train pulls out of the station just after Bond has the shoot out in the tunnel we hear the sound of a steam train pulling away with wheel slip, but the wheels are not slipping at all.
Audio problem: In the opening scene, Bianca says to Bond, "They moved the flight up to this afternoon", but her mouth does not match what she is saying.
Answer: It wasn't meant to be related at all. It was just an action sequence to start off the film as Bond completes a previous assignment before a segue into the familiar 007 opening theme and a new song. I recall there were some other earlier Bond films that also used this formula. After the opening bit, the story starts as Bond meets with "M" for a new mission, then a briefing with "Q" about the latest spy gadgets. There was also the obligatory flirtatious banter between Bond and Miss Moneypenny.

I see what you mean. I'm thinking of those films where the opening scene has some link to the main plot (e.g. The Spy Who Loved Me), but Moonraker is like this one, it starts off (spectacularly) with Bond at the end of a previous assignment.
