In section 14.8.2.1 of the documentation,
for encoding content for DVD/VCD etc. it mentions specifing an
aspect ratio for for 'Fullscreen' (4/3), 
using 

-lavcopts aspect=4/3

This is the aspect ratio for
(S)VCD's mentioned in section 14.8.1.1.

Then in section 14.8.5, this is missing from the suggested
overall commands for encoding for (S)VCD.
For example, it says 

14.8.5.6. NTSC SVCD

mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=xsvcd  -vf \
    scale=480:480,harddup -srate 44100 -af lavcresample=44100 -lavcopts \
    vcodec=mpeg2video:mbd=2:keyint=18:vrc_buf_size=917:vrc_minrate=600:\
vbitrate=2500:vrc_maxrate=2500:acodec=mp2:abitrate=224 -ofps 30000/1001 \
    -o movie.mpg movie.avi

where I should be:

mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=xsvcd  -vf \
    scale=480:480,harddup -srate 44100 -af lavcresample=44100 -lavcopts \
    vcodec=mpeg2video:mbd=2:keyint=18:vrc_buf_size=917:vrc_minrate=600:\
vbitrate=2500:vrc_maxrate=2500:acodec=mp2:abitrate=224:aspect=4/3 \
     -ofps 30000/1001 -o movie.mpg movie.avi

(note the added ':aspect=4/3' on -lavcopts's settings.)

Am I misunderstanding something here?
With out this term, the output seemed square and not 'full screen'
on the case where I noticed this.
