I have a video that's 720x486, but whenever I master it to dvd it either goes widescreen or 4:3 with black boxes on the side. I'm exporting it out of Premiere. I've tried QT 720x486 Square (black bars on side), 720x486 .9(16:9), 720x480 square(black bars on side), 720x480 .9(16:9), if I try sending it out of premiere as an avi then when I master it to DVD the video is upside down and backwards. The Encore help says to click on the file and do interprete footage to fix the problem, but Interprete Footage is always greyed out. Anyone have any ideas?
