[MPlayer-users] mencoder videos completely out of sync...

For some of my videos I set up a quasi uniform 2-pass encoding process,
which is (taken partly from the Mencoder Doc):
mencoder "$1" -o "$2" -oac lavc -lavcopts abitrate=128 -ovc x264
-x264encopts
bitrate=512:subq=4:bframes=3:b_pyramid:weight_b:pass=1:turbo=1:threads=4
-vf scale=384:288,dsize=384:288 -srate 44100 -ofps 24
mencoder "$1" -o "$2" -oac lavc -lavcopts abitrate=128 -ovc x264
-x264encopts
bitrate=512:subq=6:partitions=all:8x8dct:me=umh:frameref=5:bframes=3:b_pyramid:weight_b:pass=2:threads=4
-vf scale=384:288,dsize=384:288 -srate 44100 -ofps 24
in the 4:3 case, in the 16:9 case I use a different dsize (512:288).
Now don't ask why I set fps to 24 and srate to 44100, but that's the way
it should be for this purpose.
Now everything worked fine until recently, when I added all the
mumbo-jumbo after bitrate=512: (except for pass=x...),
there's no audio sync anymore, and skipping in the video does also not
work, audio restarts always at the beginning ???
As the added options are video only, they should not be the problem.
Now, one question is: why does the audio counter go that fast on the video?
