I have PowerDirector 365 for the Mac. When I alter an audio's pitch or tone using the audio editor, it often plays back scrambled. This has destoryed lots of my current vidoes because when I played it as a stand alone clip, it was fine, only to later find out when I play it as part of the overlal video, it scrambles. It has been this way for nealry a year, but its gotten to the point when I can't continue like this. It's not an update problem because it has persisted for quite a while. Its not my computer either, given that its new.

Can someone help me figure out a fix to this? I know the Mac version seems to be much buggier that the PC version ever was. But if someone can help me address this, I'd appreciate it.
