the following.
  
    -vo kva:dive
    
  If you have a video card such as S3 on T23 laptop which doesn't have ability 
to downscale, you can use 't23' option.

    -vo kva:t23

  If you want to set audio buffer size, do the following.
  
    -ao kai:bufsize=size
    
  Where, size is in samples. Its default value is 2048.

5. Environmental Variables...
-----------------------------

5.1 MPLAYER_HOME
----------------

  Specify the directory where configuration file exist. If this is not 
specified, use 'HOME'. But it is '%HOME%\.mplayer'. And if this is specified 
neither, it is the '.mplayer' directory of the directory where MPlayer is 
installed.

  ex) SET MPLAYER_HOME=x:\mplayer
  
5.2 MPLAYER_OPTIONS
-------------------

  !!! This is not supported any more. Instead use configuration file. !!!
  
  It is 'config' file in the directory where 'MPLAYER_HOME' specify. The 
following is example.

    # Write your default config options here!
    quiet=yes
    vo=kva:dive

This is the same as the following.

    MPLAYER -quiet -vo kva:dive
      
5.3 MPLAYER_CODECS_DIR

  ex) mplayer -codecpath x:\mplayer\codecs

5.4 MPLAYER_PATH
----------------

  Specify the fully-qualified path of MPlayer. This is for Mozilla plugin. If 
this is not specified, MPlayer in 'PATH' is executed.

  ex) SET MPLAYER_PATH=x:\mplayer\mplayer.exe

pipe should be

    \PIPE\MPLAYER\pid
      
  where, pid is process ID of MPlayer.
  
  For details, see 'slave.c' of source package.
  
  For slave commands, see 'slave.txt' in DOCS\tech directory
  
7. Using Win32 binary codecs

  To use this feature, you need a Win32 binary codec package. You can get it 
the following.

    http://www.mplayerhq.hu/design7/dload.html
    
  Then, extract all the files to the directory specified by '-codecpath'

plugins directory. 

  You can use the same key as MPlayer, and invoke popup menu when pressing
