[MEncoder-users] Bug: Mono show 2 channels????

[GeBu]

Hi,
I encoded video from DV camera, which I cut and export by KDEnlive. I 
use this mencoder script (on Debian Etch):

**      1. PASS         **
mencoder in.avi -o /dev/null -oac mp3lame -lameopts cbr:br=64:mode=3:aq=0 -ovc x264 -x264encopts bitrate=700:pass=1:turbo=1:qcomp=0.8:frameref=5:bframes=4:subq=6:me=umh:b_pyramid:weight_b:partitions=all:8x8dct -vf pp=lb,scale=768:576 
-aspect 4:3
**     2/3. PASS        **
mencoder in.avi -o out.avi -oac mp3lame -lameopts cbr:br=64:mode=3:aq=0 -ovc x264 -x264encopts bitrate=700:pass=2:qcomp=0.8:frameref=5:bframes=4:subq=6:me=umh:b_pyramid:weight_b:partitions=all:8x8dct -vf pp=lb,scale=768:576 
-aspect 4:3

I have  -lameopts cbr:br=64:mode=3:aq=0, but when I play output video in 
mplayer it shows me: 2 channel. In VLC it shows 1 channel
What is wrong?
