Audio problem: When Magneto is saying "Strange. What would restore your...," his mouth remains wide open and unmoved after saying "restore," which would make it impossible to then say "your." (00:19:45)
Audio problem: When Storm is saying "But I do know that his thoughts were with us today," her mouth isn't moving. (00:19:00)
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.
