Batman's special commands need some help

hi, i have downloaded the Batman and tried to convert a movie that has 2 languages and i tries to use the special command -aid 2 but it seems that the batman does not recognize a part of the commands like:

-subfont-autoscale 0 -subfont-text-scale 10 custom subtitle font size (here 10 pixels)
-subcp enca:pl:cp1250 (guess that subtitles are Polish, fall back to cp1250)
-vf-add scale=220:320,crop=240:320,expand=240:320:::1 correct egg-heads by 20 pixels in height (240-220). values >240 do the opposite
-vf scale=240:320,rotate=1 stretch/shrink video to fit (produces egg-heads)
-lavcopts acodec=mp2 use mp2 instead of mp3 for audio (Rockchip-based players)
-lavcopts abitrate=192 use your own audio bitrate with any preset profile
-oac copy do not reconvert audio, keep the original
-af volnorm=2:0.7 boost the volume if normalized audio is still too low
-ofps 25.000 manually set the framerate to 25 fps (or any other value)
-aid 2 use the second audio stream in a dual-language AVI
-xvidencopts bitrate=240 -lavcopts abitrate=128 use custom video and audio bitrates with Qx

Any ideas on how to switch the language ? or use the other commands ? also tries to use the special commands as parameters on the shortcut

...

- if you double-click BatMan rather than drag something onto it, you will get a language selector (this happens automatically on first start)
- there is a built-in help in BatMan which you can invoke by entering "?"

1) what does batman's language has to do with the dual audio stream in the movie ?
2) the built-in help does not say anything about the special comands that i mentioned above

1) nothing, I had just read read "Any ideas on how to switch the language" and misunderstood you.
you posted the solution yourself :
-aid 2 use the second audio stream in a dual-language AVI
2) right. these commands are part of MEncoder, and documented there. Don't confuse them with BatMan's "special commands". BatMan offers to use these parameters by typing the special command "switch".
