I have handful of video files (generated as .mov by quicktime) that lose their sound when I convert them for iPod. I tried using the contextual menu in iTunes and I tried using quicktime pro. Either way the picture comes through fine, but the sound does not - even when I try to play them on my desktop machine. Any hints?
