Audio problem: The amount of crowd noise during Joe McTaggert's speech is inconsistent with how many people are shown in attendance. The noise would suggest at least a couple hundred people, but shots of the crowd only show a few dozen. (00:08:25 - 00:10:20)
Audio problem: When Joe McTaggert is saying "If the boy shows up, keep him out of sight until after the vote. If you don't, all of our work will be for nothing," he has suddenly lost his Scottish accent. (00:07:40)
Answer: Chris Potter, the original Gambit voice actor, did indeed quit the role in the 4th season. His last episode was The Phalanx Covenant Part 1 so it seems reasonable that Fox would limit the use of the character even though it was recast. It doesn't appear that Potter left the role due to animosity, he stated in an interview that he wished to play Gambit in the first live action X-Men film.
