Contradictory; if it's fine, why is it playing at twice speed? How do you know it's fine? Does it play fine in some other app?
So you're saying that a clip that is ten seconds long exhausts the video media in five seconds while the audio continues for the full 10? What do you see when you run out of video? What happens if you unlink the clip and delete the audio from the timeline? Try doubling the time of the clip, what does it look like? What are the properties of the clip? Did you actually capture video at 15fps? What else have you tried so we don't waste our time making unnecessary suggestions?
