audio longer than video problem when converting, please help

[stephenw]

Hi All

Im new to dvd authoring and just need some advice. I know the basics etc

I have an avi file, checked it with gspot, its an xvid with mpeg1 layer 3 mp3 audio.

first i'm trying to extract audio using virtual dub mod, i open avi file, it comes up with an error saying it detected improper VBR audio. when i click no to it, then save the wav, the audio comes out fine at 43.50seconds long. When i select yes in the error box, it saves wav at 42.29 seconds long, but the end of the audio of the wav is missing.

The original video length is 42.29 long.

Can anyone help me, im confused as to why the audio length would increase further than the actual video length. and how do i sort it so the full length audio runs the same length as the video.

thanks to anyone who can help
