MPEG-2 Question

[David Thrasher]

I just upgraded to Quicktime 6 and bought the Pro license and bought and downloaded the MPEG2 component for playback of these files. I have a MPEG-2 file that was sent which I can play fine but when I try to export it into another format (have tried a regular Quicktime Mov and a DV file) the audio is missing. What gives? I'm trying to convert it into a format that my friend can view. He doesn't have MPEG-2 capabilities.
