When converting DV files to DVD (MPEG2) I currently run the video

Is it OK to assume that, if a bad video frame is detected, and is
dropped, the corresponding audio chunk is dropped too?
The reason why I'm asking - let's say I choose to run the audio and the
video encoders in two separate steps. In that case, if a video frame is
bad and is dropped, the audio track after that will get out of sync by
one frame, is that right?
Run audio and video encoders in two separate steps, but only the audio
encoder under transcode. The video encoder is a separate application,
that may or may not flag bad frames the same way transcode does.
See my dilemma? What happens if I use a totally different transcoder for
the video track, and there are some frame drops? How do I guarantee that
audio and video are still in sync?
I can't feed video from transcode to the other encoder via a pipe - the
other encoder is a Windows application running under Wine, and it needs
an actual source file to read.
