Through my research of finding a camcorder, I come up with this question. How does iMovie 09 interact with 1080i AVCHD video? I see there's an option to import it as 960x540. Now if I did that, would iMovie automatically de-interlace the video? If it does, then what would happen to the original video? If iMovie 09 downscale the video, then what would it use for the 720p output? So many questions, and it's hard combing through the anecdotal experiences online.
