i shot letterbox but it looks stretched on imovie. would squeeze setting be better? is there more settings in imovie other than 16:9 or 4:3. should i just shoot norm(4:3) and forget widescreen? i know imovie is limited but will it be the same in fcp?

in short, how can i shoot widescreen using dvx100ap and imovie and have it look good?
