That commandline should read:

mencoder dvd:// -dvd-device SOME.iso -alang en -passlogfile /tmp/dvdrip_31156.temp -ovc x264 -x264encopts bitrate=860:pass=1:turbo=1:threads=1 -vf crop=718:572:0:2,scale=-1,dsize=1.33845 -oac copy -slang nl -o /dev/null -of avi

The bitrate was missing, which is only in the output of my script, not on the actual command, which you see in this post.
