HD import footage out of sync in Final Cut Pro X.

I am finally using my Final Cut Pro X and just got a Canon Vixia HF G10. I imported my first footage just a quick sample - only 25 seconds. The audio is not in sync with picture. In iMovie HD it plays perfectly but I need to use Final Cut Pro X. This picture also seems jumpier - not sure why. I have an importance project to get going on and need some help in fixing this problem.
