I have a 2.35 aspect ratio video in an AVI file that I want to burn to letterboxed 16x9 dvd. I tried to export the file to MPEG-2 but it only had 4:3 and 16:9 ratios. What I want is the original 2.35 video with black bars on the top and bottom in a 16x9 dvd. How do I do this in Quicktime? Or any other software if QT can't do it? Thanks.
