[MEncoder-users] H.264 with pre7 works, with pre8 does not

[GeBu]

I have this skript:

#!/bin/bash
mencoder $1 -o /dev/null -oac mp3lame -lameopts cbr:br=48:mode=3 -ovc x264 -x264encopts bitrate=${3-"1500"}:pass=1:turbo=1 -vf pp=lb,scale=512:384 -mc 0 -noskip -aspect 4:3
zmencoder $1 -o $2 -oac mp3lame -lameopts cbr:br=48:mode=3 -ovc x264 -x264encopts bitrate=${3-"1500"}:pass=2 -vf pp=lb,scale=512:384 -mc 0 -noskip -aspect 4:3

It works with pre7 (my friend has it), but it does not work with pre8 (I have). Both we use marillat: www.debian-multimedia.org, but I updated.
What is new with pre8?
