[MPlayer-users] encoding with xvid does not honor bitrate argument?!

Hi!

I have the following problem: I want to encode a set of .vob as follows:
cat *.vob | mencoder -oac mp3lame -ovc xvid -xvidencopts bitrate=1600:pass=1 -v -sid 0 -

But the bitrate/filesize I get is way to big. In fact the file created
at the first pass is even bigger then the original .vob.

Here is the output of a run which has been interrupted after a bit of
time:
