This gives the syntax error:

"C:\Bin\mencoder.exe" "C:\Bin\BS04E23.mkv" -o "D:\enc_out\BS04E23.mkv"  -ovc
x264 -x264encopts
threads=0:bframes=2:b-adapt=2:partitions=all:cabac:nopsnr:nossim:frameref=2:me=umh:merange=16:subme=6:trellis=0:psy-rd=1,1:bitrate=1800
-oac lavc -lavcopts acodec=vorbis:aq=5

Take off the :qa and replace with any abitrate and you get ~52K vorbis no
matter what, according to mediainfo and my ear.
