audio sync with tmpgenc

[kerrang]

I have a problem with a dvd rip and audio sync when encoding a svcd mpeg and tmpgenc 2.57.
I ripped the dvd with smart ripper and used dvd2avi then when encoding with tmpgenc the audio on both the film and the extras is out of sync by about a second.
Another dvd rip I have on my hard drives encodes perfectly so I`m wondering if the problem lies with smartripper or dvd2avi.
any help would be great...

After ripping aaaaand convert to avi is sync stil ok?

if so....
extract the audio using Virtualdub and save as uncompressed WAV ,then use resulting WAV as audio source in TMPGE.
