Audio Video Sync Issue

When I use Dvdfab to transfer DVD to a micro sd card for my cell phone the audio is out of sync with the video. My phone is a Motorola Krave ZN4 and my Dvdfab version is set to LG VX9400 3gp because that gives my phone the best resolution of all the options I have tried so far. Also I am using Window XP. Does anyone know how to resolve this issue. The DVD’s I have tried are Zoom, and Thrillbillies 2,3,and5 “Nitro Circus”
