no sound when converted

hi,
i have a avi movie file.
when i try and convert this to a mpeg using tmpge.
it has no sound.
i have extracted the wav file, which on it own is fine.
also tried cce which also gives an audio error.

AVIcodec reports it as.
25.0 fps, 576*240 (2.21:1), XVID = XVID Mpeg-4, Supported
48000 Hz, 5 channels, 0x2000 = AC3 DVM, Supported

and as can be seen i appear to have the codecs for it.

the file plays fine as an avi, but i wish to put it on a vcd so i can watch on my dvd player.
