Is there work in progress with ac3-encoding? Leaving out my speed options doing

=============
mencoder -demuxer lavf -ovc x264 -vf 
pp=fd,hqdn3d,delogo=1132:48:48:80:5,softskip -x264encopts

I get sound like someone pushed fast forward. Doing the same with mp3lame I get 
the usual behaviour:

=====================
mencoder -demuxer lavf -ovc x264 -vf 
pp=fd,hqdn3d,delogo=1132:48:48:80:5,softskip -x264encopts
