The command I used was

 mencoder -oac lavc -ovc lavc -of mpeg -mpegopts
format=dvd:tele_src=24000/1001:tele_dest=25 -vf scale=720:576 -lavcopts
vcodec=mpeg2video:vrc_buf_size=1835:keyint=15:vrc_maxrate=9800:vbitrate=5000:aspect=4/3:acodec=ac3:abitrate=192
-fps 24000/1001 -o ./dvd.mpg movie.avi

any suggestions.

The thing is it looks good on the computer but not so good once on the dvd.
