When capturing from a Mini DV tape in FCE4, the audio syncs ok at first. When creating subclips from the master, the audio sync goes off by 2 seconds and corrupts the master clip as well. These are originally VHS tapes converted to DV tape, by the camcorder. I've always used the 12 bit audio setting in the camcorder for all my Mini DV tapes and hope this is not an issue. This was not a problem for me in Imovie6.
