I think someone in this thread said it can be done, but i've tried to no avail. I just take still's out of imovie if i like a pic but can it be done?

I don't have an HFS200, but on the HF-11, I just press the photo button (on the remote, or on the camera if you're brave) while recording. I do have the images set to 1920x1080 to match the video frames, though. These images are kind of fun to post on Facebook after the shoot to get people excited about my projects.

Page 114 of the manual tells you how.
