How to make iMovie Export Full HD?

"Hello, I just purchased a Canon HF200 and after a long day of shooting on vacation I put my 16GB, 6 class memory card into iMovie 09 only to discover that it would only let me import at "Large 960x540" and "Full-Original size," no selection for "Full- 1920x1080." I know my settings are set at the highest quality on my camera (At least I believe.. MXP right?). I've searched the web trying to find the answer to this but obviously no luck. Any help would be greatly appreciated.
Thanks."

The truth is
“Both iMovie 09 and iMovie 11 can do this. For 1920×1080 footage, you will want to import as “Full” rather than “Large”.
In iMovie 11, there is a 1920×1080 pre-set.
In iMovie 09, you may need to SHARE/export use QuickTime and then choose h.264, 1920×1080 and a high data rate (16Mbs or higher) in the video settings. It has been a while since I used iMovie 09.”

Here is the detail guide step-by-step.
After finish the editing on iMovie, go to share.
Share > export use QuickTime.

Drop formats menu->Select here “save as MP4″, change MP4 drop-down to MP4 (not MP4 isa or whatever) and fill in the values seen in the following screen shot.

All done. In one step, directly out of iMovie. No special software, add-ons, helper utilities (like the duo JES Deinterlacer and MPEG Streamclip) required.
