iMovie can no longer export to camera after installing Final Cut Pro HD or Final Cut Express HD

After installing Final Cut Pro HD or Final Cut Express HD, you can no longer use iMovie to export to a DV camera connected via FireWire.

You may see the following alert:

Lost connection to camera.
iMovie lost the connection to the video camera. please check the connections and try again.

This can happen with iMovie 3 or iMovie 4. This does not occur with iMovie HD 5.0.

The solution is to temporarily move the following files from /Library/QuickTime/ to the Desktop:

Final Cut Pro HD

• DesktopVideoOut.component
  
• DVCPROHDVideoOutput.component
  

Final Cut Express HD

• DesktopVideoOut.component

Restart the computer and try exporting from iMovie to your camera.

When you need to use Final Cut Pro HD or Final Cut Express HD again, drag these files back to /Library/QuickTime/ and restart the computer.
