I understand, I used to use similar programs, and appreciated that they
took my ffmpeg created input without reencoding.

But: mpeg2video is a much more effective codec for DVD. ffmpeg even has
a shortcut-option "-target dvd" (or "-target pal-dvd", "-target
ntsc-dvd") which sets several encoding options for DVD compatibility.
