Try the free SlickSampler from GeeThree; it has a Rotate Clip.bundle which gets installed in your user library's iMovie folder. Post back to let us know if it worked for you.

I have a clip from my digital camera that I filmed in portrait mode, downloaded it into iPhoto. Is there anyway to change the orientation to landscape in iMovie? I can't afford to update to iLife '09 right now. I've tried searching for an add-on but can't find one. AAny help would be appreciated, thanks.
