i keep tring to burn this movie that my brother sent over and the audio keeps lagging the video is ahead of the audio
Are you burning as data or converting and burning for use in a standalone DVD player?
I'd guess converting, in which case try a different tool. ConvertXtoDVD is one of the better choices (not free), DVD Flick and FAVC are also decent (free).
if its a data file,try nero showtime first,this will show if the sound and picture are in sinc,if not leave alone rubbish in rubbish out is the key word here. if its ok dvdflick is a good free program to change to dvd .
