[MPlayer-users] Segfault in mencoder when using -vop scale..

After reading all the mencoder docs I can find, I'm having
a go at converting a DVD to DivX using the three-pass 
encoding referred to in encoding-tips.html.

mplayer -vop cropdetect suggests "crop=720:432:0:72". If I
use that with no scaling then I get a successful encode
but the aspect ratio is wrong since it's a 16:9 DVD.

If I add "scale=720:304" then mencoder prints:

crop: bad position/width/height - cropped area is out of the original!

then it segfaults.

Platform is FreeBSD 4.8 using mplayer, which is
the most recent port (unless it was updated in the last day).

BTW a recent post mentioned that 3-pass encoding was buggy.
Is this one of the known bugs?
