I'm trying to rip and encode a segment of a dvd using the following command:

mencoder dvd://1 -chapter 7-7 -oac copy -ovc lavc -lavcopts
vcodec=msmpeg4v2:vbitrate=3072 -aspect 16:9 -ofps 24000/1001 -endpos 129 -vop
crop=720:405:8:58,scale=736:522 -o

which works just fine. But when I play the video back with mplayer I see:

VIDEO:  [MP42]  720x405  24bpp  23.976 fps  2128.9 kbps (259.9 kbyte/s)

So, why is the video bitrate of the resulting file not the sames as what I
specified (3072)?
