Kopkoonkrub! Thanks for the answer. So if I work with Pal Square pixel then the images or the footage I see should be correct. Circle will appear to be Circle. Is this correct? if it is correct then I assume that when I click the Toggle Pixel Aspect Ratio Correction in an D1/DV PAL (1.09) comp and the comp stretches out on the side is the correct view (Circle will appear to be Circle). If I get anything wrong please tell me. I will get to read the article. Thanks again.
