Camtasia 9- MP4 export, audio out of sync just slightly?

I just upgraded to Camtasia 9 last night. I exported a video several times today. When I look at it in the timeline, the audio and video are in total sync (they were shot using the same device for audio and video). When I view the exported MP4, the audio is lagging just a small amount but enough to notice when lips are moving early. 

The odd part is when I upload the file to Vimeo, it looks to be in sync again. The raw MP4 though is off. Any ideas why this is and what I can do to fix it?
