Record Video in iMovie 09 with Audio From Garageband

I plugged my POD X3 into my Mac and opened up Garageband, I imported the backing track into Garageband as I wanted to record myself playing over it. I set the audio in both System Preferences and Garageband preferences to have the audio input and output coming through the POD X3.

I hit record on iMovie and I got the sound of my guitar perfectly but no backing track! When I tried to import the backing track into iMovie I can't get it to sync up... Anyone have any ideas?

???? Why are you hitting record in iMovie?? It has nothing to do with GB!

I thing what you want to do is: Import the backing track into iMovie and place it in the project as needed.

To record yourself in iMovie, use Voice Over:

Otherwise, record yourself as an instrument in GB and export the combined backing track and yourself to a single audio file (i.e. Share to iTunes - uncompressed - and your recording will be available directly from the iMovie media browser). Place the combined file where you need it in the iMovie project. This gives you that advantage of having access the GB amp modeler and stomp boxes.
