I am using MC 4.0.5 and finishing up a long project. I am exporting the films with Quicktime 3 on my AVID. I always do a mix down of audio files and they sound great. Simply mixing dialogue, narration and music. It all sounds fine on the AVID. However, whenever I do an export, the sound is scratchy -- I don't know how else to describe it. Any ideas what is going wrong? And what I should do to help??
