This release of VMPEG is a demonstration version. For this reason audio is
restricted to 15 seconds and stereo decoding has been disabled.

VMPEG is copyrighted software, (C) Stefan Eckart, 1995. You may use, copy and
distribute this program solely for demonstration purposes, only in unmodified
form and without charging money for it. Commercial use of this demonstration
version is strictly prohibited.

Disclaimer: This program comes without any warranty. You are using it at your
            own risk. 


2. Installation
===============

- create a temporary directory, e.g.

    MD VMPEG.INS

- change to this directory

    CD VMPEG.INS

- run the self-extracting zip-archive VMPEG15.EXE

    ..\VMPEG15

- run the setup program (from either DOS or Windows)

    SETUP

The setup program will ask you if you want to install the WinG runtime
libraries. Installing them usually improves performance considerably. On the
other hand there are some graphics cards which are not entirely compatible
with WinG. In this case you may have to de-install WinG as described below.

Be aware that the installation of WinG may overwrite an existing dva.386 in
the windows\system directory. It may be a good idea to make a backup of this
file before installing WinG. Otherwise you might have to re-install the
Windows drivers for your graphics card (in case you run into problems with
WinG).

If you start VMPEG (or any other program using WinG) for the first time, a
performance test window appears which adapts and optimizes WinG for the VGA
in your PC. This may take several minutes.

The setup program performs the following steps:

- if you choose to install WinG:

  - copies the files wing.dll, wing32.dll, wingde.dll, wingdib.drv,
    and wingpal.wnd to the windows\system directory.

  - copies dva.386 to the windows\system directory and adds a line
    'device=D:\WINDOWS\SYSTEM\dva.386' to the [386Enh] section of
    system.ini (only for Windows 3.1x)

- copies vmpegwin.exe, vmpeg.hlp and readme.txt to the directory you
  have been prompted for

- creates a program group and program entries for VMPEG, the
  associated help file and for the readme file in the program manager

- asks you to restart Windows (only if dva.386 is installed and has
  not been installed earlier)

To de-install VMPEG and/or WinG simply reverse these steps manually.


WinG is also available separately from:
    
    ftp.microsoft.com:/developr/drg/WinG/WinG10.ZIP

and via CompuServe.
