After I edit the sequence in Pre Pro I export the audio, then once the audio is edited using Audition, I mixdown, Eq, Hard Limit and save as a PCM Wave file, then import it back into Pre Pro and replace the old audio with the edited wave file … When I export out of Pre Pro I export as an AVI file then transcode in Encore … I still think you have some problems in your system causing your problem ………….
