2. Notes

ProjectX needs to be in default (demux) mode to do it's all-important fix ups.
mplex is better at multiplexing than ffmpeg
you can pull commflag info out of mythtv to use as chapter points in the DVD

2.1. letterboxed 4:3 in 720p to DVD-Video

ffmpeg -r 60000:1001 -i 1171_20070330013000.m2v -cropleft 160 -cropright 160 -target ntsc-dvd -aspect 4:3 -b 4600000 -an -f mpeg2video 1171_20070330013000.dvd.m2v
