I encoded a 2.35:1 DivX movie using TMPGEnc to DVD and burned it. When encoding the movie, I set the aspect ratio flag to 16:9 and used the setting "no margin, keep aspect ratio" under the "clip frame" option. When I burned the final movie, it came out as 1.85:1 instead of the original 2.35:1. Obviously "no margin" is the incorrect setting. Which one is?
