On a quick skim-through, it seems to be perfect in some places, and close-but-not-quite-there in others.
Have you been syncing to the video, or to the GOUT audio? I feel it'd be easier to sync to the audio instead of the video, myself - you can tell when audio's out of phase by listening to both simultaneously much more easily than guessing if the audio is drifting or not from watching it with the video.
