iMovie 08 Export Error Message

I am trying to export from iMovie 08 without any success. I repeatedly get the same error message, but cannot find any reference to the error number anywhere. The error code is -2000. Here is the process that gets me there.

Import video from Canon Vixia HF m31 AVCHD camcorder to iMovie 08. Video was shot as PF30 (wrapped in 60i in-camera). Imported as "FULL". Trimmed a few seconds from the beginning and end. Share to "Export using Quicktime". Settings in Quicktime:

Compression: h.264
Frame Rate: Current
Key Frame: 24
Frame Reordering: YES
Compressor Quality: High
Encoding: Best (Multi-Pass)
Data Rate: Automatic
Size: 1280x720HD

Prepare for Internet Streaming: Fast Start

Am I doing anything wrong with any of these settings? The movie does start to encode, but about 1/2 way thru I get the error message. Does anyone have any idea what that error code means?
My export destination is Internet streaming, preferably at 720p for nice full-screen viewing.

Other tools I already have: iMovie HD, JES Deinterlacer, MPEG Streamclip, Quicktime 7.6.6

Thanks in advance for any help you can offer.
