xvid conversion no sound???

[cellardoor]

I'm trying to convert an xvid. Done many before, but never had this problem. It shows that it has no audio??? When I play the file before the conversion I have audio after nada. I have the ac3 codec installed is there another codec that I need??? If so please let me know. Thank you

tried convert the audio to wav and use it as audio source in your converting tool? www.videohelp.com/virtualdubaudio
