The same happens also with

mencoder movie.vob -o movie.avi -ovc x264 -x264encopts 
subq=1:frameref=1:weight_b:pass=1:threads=auto -ofps 24 -delay 0.0 
-audio-delay 0.0  -oac mp3lame -lameopts abr:br=64:mode=3:padding=2 
-srate 44100 -vf scale=384:288,dsize=512:288

and no x264-options at all.

and no lameoptions, srate, delay, audiodelay, ofps...:

mencoder movie.vob -o movie.avi -ovc x264 -oac mp3lame -vf 
scale=384:288,dsize=512:288

removing dsize doesn't help either.

So it doesn't have to do with the container (and as long as it plays 
with mplayer, I'm happy about it).

-v delivers the following:

Exiting...


I reckon the video has some sort of resolution change at the and or how 
do I interpret this?
