TMPGEnc Audio Sync Problem

[XooL]

Hi guys, Im trying to encode a xvid wiv TMPGEnc which i have done like 100 times before but for some strange resion the output is always out of sync so i thought hay it must be the movie so i tryed another movie and its still out of sync?? Any1 know wot this prob can be?? will it have something to do with the environmental settings?

This is how i encode the xvid:

1: Strip audio wiv virtual dub and save a .wav
2: Open TMPGEnc load the audio and video
3: Choose my settings like pal/ntsc then CQ 100
4: Click Start,

I have done that 100 time before and its work fine now i tryed like 4 diffrent movies and they all are out of sync... Can some1 please help me ...thanx

Have you tried encoding without using an extracted audio?
(I only extract WAV from Divx but not Xvid,,,,works for me .,..no sync probs

Actually im having the same problem - I convert a 29.9fps movie to a 25 fps movie, and then when I demux them, and put them in a DVD authoring program, it desyncronizes, the movie is going a TINY bit faster than the audio. and also, I NEED to demux them because the dvd authoring prog will only accept demuxed files!!!
