For 1080i ATSC files the following works for me:

mencoder -of mpeg -mpegopts format=dvd:vbitrate=8000 -oac copy -ovc lavc -lavcopts vcodec=mpeg2video:vbitrate=8000:keyint=18:mbd=2:aspect=16/9 -vf scale=720:480:1 -fps 30000/1001 -vc mpeg12, -o foo.mpg foo.nuv

You must also pass -v 16:9 to dvdauthor, since the resulting mpg file
has a non-square pixel (16:9 aspect in 720x480).
