While I think the this edition of Star Trek: The Motion Picture is good, there are some problems.

During the scene where Kirk, Spock and McCoy talk about the Intruder after they successfully went into warp, there is a quick second of nothing but black during their conversation. It happens just after McCoy says "Well, isn't it lucky for you that we just happen to be heading your way."

There is also some audio sync issues, especially during the beginning of the scene listed above and where Scotty is talking about why Kirk would order the ship to be set on self-destruct.
