TMpge problem

When trying to convert an xvid to mpeg to burn with tmpge how is it done? so far it converts the image but it has no sound. I remember something about having to ajust something but I cant remember what it is and I cant find the info

can someone help please?

If your source is DivX / XviD it is best to extract the audio separate to a wav with Virtualdub because TMPGEnc can not handle all audio sources that well (causes sync problems).
