This occurs randomly on Windows systems if you have QuickTime Pro installed on your computer.
When you try to import a QuickTime movie which has a soundtrack it may fail. If it does, then the following error message will appear: "An error occurred while importing the QuickTime movie."
Resave the movie using the current QuickTime Pro version.
NOTE: Once the QuickTime movie import fails, it will fail for ALL future imports (with or without sound). To correct the problem, relaunch the application.
