I would try the freeware FAVC or the payware ConvertX to convert your files to DVD. Both perform better than Nerovision most times.

Sync problems can be caused in several different ways. It may be MP3 VBR audio from a Xvid or Divx video. Or a bad framerate conversion, such as NTSC<>PAL, or a corrupted video or audio file, or bad cuts and pastes from editing or joining a two part video.
