why don't you simply use
mencoder serenity.avi \
-of mpeg \
-mpegopts format=dvd \
-oac copy \
-ofps 24000/1001 \
-vf scale=720:-10,expand=720:576,harddup \
-ovc lavc \
-lavcopts 
vcodec=mpeg2video:keyint=15:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=6500:aspect=4/3:dc=10:nr=300 
\
-o file.dvd

I know that there are sync and buffering problems when using telecined 
content, but so far no one ever reported
that the ac3 audio track couldn't even be identified/read
