mencoder video_pulldown.m2v -of mpeg -mpegopts format=dvd:telecine:vaspect=16/9 -ovc copy -oac copy \ 
-audiofile audio.ac3 -audio-demuxer 20 -rawaudio format=0x2000:bitrate=<BITRATE> -o title2.vob

dvdauthor ... title2.vob

and test the resulting dvd with your standalone player

even better: send me the output of
$    mpeg2desc < title2.vob | grep -B 1 pts | less
