A standard NTSC DVD video is 720 x 480 pixels (width and height), while a standard PAL DVD video is 720 x 576 pixels. Since a PAL DVD video's height is more than that of NTSC DVD video, the aspect ratio of the source video is lost. Moreover, because the video has to be resized, some loss in quality is expected. When using the DivX or XviD video compressor for converting to AVI, you might get inverted videos. This is a problem related to the compressor. You can use Digital Media Converter's Effects feature to flip the video to correct the inversion.
