If you install the QuickTime 6.5.1 update before the Mac OS X 10.3.3 update, the Apple Lossless codec will disappear from the list of available compressors for audio export in the QuickTime Movie Sound Settings Export Options dialog.

Products Affected

QuickTime, Mac OS X 10.3

To avoid this, install the Mac OS X 10.3.3 update before updating to QuickTime 6.5.1.

If you have updated and are missing the Apple Lossless codec, reinstall QuickTime 6.5.1 or later. It's available from the QuickTime website.
