Joe-
Did you ever get a solution to this problem, i was going to post with the exact same issue. 1-how to import as dual mono not stereo and 2-if i needed to change the speed on the audio. the film, shot on 720p video at 23.98. so is the solution to slow down the audio 4%.
i tried to multiclip the video and audio. i think by doing this, it made the audio mono, but the sync was way off.
