Importing to iMovie: How do I use an external usb mic when recording with the built-in FaceTime HD Camera?

Hello all

I'm scheduled to work with a friend this week; I'm going to help him make a simple audition DVD. I promised him I had the necessary equipment and such.

I was importing from the webcam using iMovie. If I can't use my external mic to record for the video, there is more involved in the editing process. I was hoping to record the video and audio into one package. I'm using the built-in FaceTime webcam on my macbook pro and a ZoomH1 on usb.

I've tried changing the audio in system preferences: input to H1. This works when recording with audacity or anything else. I even changed the input on FaceTime to H1. There aren't any preferences I can find in iMovie to change the input for importing video directly from the webcam.

How do I change the audio input for direct import on iMovie?

OR

Is there something else I can do to have HD video and HQ audio captured in one video file on my macbook pro?

I suppose I can record the video and audio separately but that is usually much more involved. This is why I got this usb microphone lol.

Thanks in advance,
