Yea. In DVD Studio Pro, if you want to author a sequence that is 16:9, there is a parameter in DVDSP labeled “Display Mode.” If you select “16:9 Letterbox”, it will automatically scale down your video to letterbox when the DVD sees a 4:3 TV, but it will also completely fill a 16:9 TV if it sees that. I’ve done this many times. It works. There is no need to bring your 16:9 sequence into a 4:3 sequence so that you can manually letterbox in your NLE.
