Converting to ipod video not working

[artefact2001]

i'm trying to convert mpegs to .mv4 format in quicktime, but everytime i try, i lose the sound. I'm using Quicktime player 7.1.3 pro and exporting 'Movie to iPod' at default settings, anyone know why my movies become silent?
thanks

Try using isquint. http://www.isquint.org/
Fantastic program. probably faster than the quicktime pro conversion and should keep sound and all that intact.
