  converting MPEG-1 video and system (video part only) streams
  to AVI file format.

-----------------------------------------------------------------

  * Windows 9x/NT4.0+ or compatible
  * 0.3 MB of disk space
  * AVIFIL32.DLL, MSVFW32.DLL and MSACM32.DLL 
    in Windows System folder

  USER'S MANUAL
-----------------------------------------------------------------

  Usage: mpeg2avi <mpeg_file;luminance_scheme> <avi_file;codec> 
                  <num_frames>
 
  MPEG luminance scheme for image decompression (optional):
    m - from MPEG Software Simulation Group, darker (default)
    b - from Berkeley MPEG Tools, lighter

  List of codes for common AVI codecs (optional):
    cvid - Cinepak by Supermac (default)
    dib  - No compression
    msvc - Microsoft Video 1 (max. 15-bit)
    iv32 - Intel Indeo R3.2
  * to use other, just enter its four character code
  * if no codec is assigned with the prefered four caracher code
    a window containing all supported codecs will be raised

  Note: by default all frames are converted if not specified 
        different by <num_frames> parameter

  Example: mpeg2avi "c:\mpeg clips\video.mpg";b vidclip.avi;iv32

  Mpeg2Avi is a console application, meaning that it should be 
  used from MS-DOS prompt. It's something like 32-bit DOS 
  program, you cannot click on it from Windows.

  The simplest way to convert a MPEG file using Mpeg2Avi:

  1) extract Mpeg2Avi-1.2.1.exe archive to c:\mpeg2avi folder
  2) start MS-DOS Prompt (Start -> Programs -> MS-DOS Prompt)
  3) type: cd \mpeg2avi
  4) if you want for example convert a MPEG file video.mpg 
     stored in c:\clips folder execute the following command: 
     mpeg2avi c:\clips\video.mpg video.avi
     Note: in this case the output AVI file will be stored in 
     c:\mpeg2avi folder

-----------------------------------------------------------------
  WHAT'S NEW
-----------------------------------------------------------------

  Mpeg2Avi 1.2.1
  --------------
  * command line delimiter changed from ":" to ";"
  * fixed few bugs with some MPEG file subformats
  * improvements to AVI codecs selection window

  Mpeg2Avi 1.2
  ------------
  * number of frames to convert may be specified as third 
    command line parameter
  * selecting prefered AVI codec through its four caracter code
  * decompressing MPEG images using different luminance scheme
    from MPEG Software Simulation Group, previous scheme from
    Berkeley MPEG Tools may be also selected with :b parameter
  * modifications that ensure valid AVI file on output in case
    of error when reading input MPEG
  * slighty changed parsing of command line parameters

  Mpeg2Avi 1.1
  ------------
  * much faster MPEG decoding resulting in significant overall
    speed increase
  * MPEG-2 extensions abandoned for better stability

-----------------------------------------------------------------
  WHAT ABOUT AVI TO MPEG ?
-----------------------------------------------------------------

  We could easily make such an utility but it already exist. 
  Go to  http://www.mnsi.net/~jschlic1  and look for Avi2Mpg1. 
  This free utility can also convert the audio part of an AVI.

-----------------------------------------------------------------
  TECHNICAL STUFF
-----------------------------------------------------------------

  MPEG -> Moving Pictures Expert Group
    MPEG-1, ISO/IEC 11172
    Partial support for system streams, audio ignored

  AVI -> Audio Video Interleaved
    Video codecs supported directly:
    * Cinepak by Supermac
    * DIB full frames, no compression
    * Microsoft Video 1
    * Intel Indeo R3.2
    other may be specified by their four character codes
