Strongly appreciate urgent advice as I need to buy before weekend. I have short-listed to Sony HDR-HC7, Canon HV10 and Canon HV20. I intend to use iMovie HD 06 for my editing. Some questions please. 1. Which of these cameras are the best? I would like the HV10 ideally for size. 2. If I choose to edit in HD mode and burn to normal DVD (which I am assuming I can do), would I get a better quality image than with a good SD camera to DVD? 3. Are all these cameras TRUE widescreen? 4. Should all these cameras work with iMovie HD on MacBook without trouble? I am sorry for asking so many questions but no-one in the stores seem to know these answers and thus I am pleading to the wise ones out there. Many thanks in advance.
