App #10 : DivX Codec

One day, you will download a video on the Internet with the .avi extension and it will simply won’t play in QuickTime. You will have no idea why, because QuickTime usually seems to open .avi. The culprit? The video has been encoded with the DivX codec. It is a very powerful codec that will compress video while still keeping a reasonable amount of picture quality. The DivX codec is available for the Mac and will integrate with iTunes. It will appear in your System Preferences Panel once you install it. Download DivX.
