Xvid convert to VCD format

I downloaded these files from bit torrent and able to open video on media player but not SOUND.

I can use player like VideoLan to play these file and no problem with the video and audio.

The problem i have now i, i would like to convert using my nero to VCD. It converts and display the video... but when i try to preview play before burn there is no audio. Am i missing any specific codec here?
