Im pretty sure this topic hasn't been discussed thoroughly ( i did a search on aec but only 2 threads came up). Ive tried max sharpness but at times, my dvd copy is jumpy when i play it on my dvd player. How does max smoothness work? i read on an earlier post that max smoothness is the best. does it blur the images to keep the video smooth? or should i stick to using just the default sharp setting?
