As a note to users who may be using the XML export or the Conformation export with final cut:
The newest version of Final Cut Pro (Final Cut Pro X) does not at this time support the import of XML files.
The XML feature is what allows us to import Storyboard Pro files into Final Cut Pro. If you are using the File > Export > XML feature, or the Conformation Export, these files will not import into Final Cut Pro X.
As such, we recommend not upgrading to the latest version of Final Cut until they have addressed this issue.
