Iím using Elements 3.0 and Iím exporting a short clip/trailer to MPEG2. Not a problem until I add a pitch shifter to the audio line, then the clip once exported, has no audio track at all.

I have tried to see what elements within my clip might have been causing this, removing, replacing, exporting etc etc, I have identified it is definitely the pitch shifter when added to the audio that causes the complete lack of audio track on the MPEG2 file.

Has anyone had this before? Is there a solution for it?

Many thanks.
