No, that's about avi and he is talking about mpeg.

For the copy of dvd mpegs this command line should do it:

(PAL)  mencoder -of mpeg -mpegopts format=dvd -ovc copy -noskip -o out.mpg dvd://1 -oac copy

(NTSC) mencoder -of mpeg -mpegopts format=dvd -ovc copy -noskip -o out.mpg dvd://1 -oac copy -ofps 24000/1001 -mc 0

If you need to change the aspect use -mpegopts format=dvd:vaspect=4/3
