(1) The film transfer on the PAL DVD is stored natively as 720x576 pixels. During playback, this information is stretched horizontally to 1024x576 resolution, which gives us the following corrected image on a 16:9 display:

(2) The film transfer for the NTSC DVD is stored natively as 720x480 pixels. During playback, this information is stretched horizontally to 854x480 resolution, which gives us the following corrected image on a 16:9 display:


It's not that simple - for a correct AR (if I remember correctly), a PAL 720x576 image should first be cropped to 702 pixels, and THEN stretched to a 16x9 frame (best not to talk about pixels at this point). An NTSC image should first be cropped to 704 pixels, then stretched to a 16x9 frame.

In short, if your final MPEG has 8 (or 9 for PAL) pixels of black on either side, these should never be visible on any display.
