I have been struggling with this problem for months.... When I edit a project on Adobe Premiere and then try to export it to a .avi file for Windows Media Player or Quicktime it never ends up playing right. It always seems to have high pitched audio like it's playing in fast forward or something. The video seems to be fine though. Even when I try to download a movie trailer into QT it has the same problem or when I play a video from a CD in Windows Media Player that I know is a working video it still doesn't play right. What do I need to download or setting I need to change to solve this problem?
