I need to do a project that will only be displayed on the web and I want the best results I can get. So using a PAL DVX would give me about 100 lines more of resolution?
No, it is still 4:3 but the pixels are not the same dimension as the NTSC pixels. But like everyone else said, if going to web based projects, you will have to downrez your footage and heavily compress it, thus negating the hassle of working with a PAL camera in an NTSC based country. If you are really worried about resolution, why not look at one of the upcoming HDV or DVCPRoHD cameras.
