2 Pass Encoding? Better A/V sync?

Suggestions: Could there be an option to enable 2-pass encoding in CloneDVD Mobile? I realize most of the time this is unnecessary, but for encoding videos such as http://www.animusic.com/ there can be a lag between when the performer hits the drum, and when you hear the drum being hit. If the sync is off even a few frames, it doesn't quite satisfy.

2 Pass would tighten that up, as well as create smoother A/V overall.

I would like to see this. It may make the conversion take longer but at least the audio would sync. Only had one movie with a problem but other people have had problems as well.
