What's up with the timing?

I have an audio track that I scrub to and try to get the character to move his hands in time with it. It seems right when I scrub through the timeline but on playback there are way too many hand cells and I have to cut some out so it’ll synch. Am I doing something wrong here or is scrubbing in the timeline view an inexact science?

Nevermind. The exported movie synchs fine, it’s just a problem with playing it inside of TB.
