I have a consumer grade Panasonic PV-GS90P camcorder. One of the setup options on it is aspect ratio 16:9 or 4:3. I've always had it set on 4:3 and always had standard definition televisions in the house. We now have two high definition TVs. Is there any pluses or minuses to changing the aspect ratio to 16:9? Am I taking the same number of pixels and spreading them out? This is a newbie question but that's how guys like me learn. From the pros.
