Introduction:

    VCD PowerPlayer is a pure software VCD and MPEG-1 audio/video 
  playing system. By using this software, Users can play VCD
  titles and MPEG-1 audio/video files without any additional
  hardware.
    VCD PowerPlayer can support CD-I, VCD 1.0, VCD 2.0, and normal
  MPEG-1 files. The frame size can be 320x240 (SIF), 384x240, 352x240,
  352x252, 288x252, 160x120, etc. LinkMPEG supports MPEG-1 Audio Layer
  I&II audio formats. The sampling rate can be 48.0kHz, 44.1kHz, 32kHz,
  or 22kHz. The MPEG-1 sequence can be audio/video, audio only, video
  only, or intra-frame only (still picture). VCD PowerPlayer supports
  DCI v1.6, DirectDraw I, II, and III, WinG and GDI display interfaces.
  It follows Digital Video MCI and OpenMPEG 1.10 specifications. Now,
  it can run under Windows 3.1 and Windows 95 operating systems. 


System Requirements:

  1. Pentium-90 PC compatible is required. Pentium-100 (or above) PC

  2. 8- or 16-bit sound card is required.
  3. 2 time speed CD player is required. 4 time speed CD player is
     recommended.
  4. 256 (or above) color VGA card is required. VGA with DCI or
     DirectDraw support is recommended.
  5. 8MB system memory is required.


Installation:

  After starting up Windows 3.1 or Windows 95 operating system, insert
  VCD PowerPlayer diskette into the floppy drive. Then, execute 
  a:\setup.exe (or b:\setup.exe) by double-clicking setup.exe file in
  drive 'a' (or 'b') under File-Manager program).

  to start the program.


Configure VCD PowerPlayer:
 
Video Display¡G
  DCI     DCI (Display Control Interface) is a display control standard
          under Windows 3.1. If your VGA card supports DCI, please
          select this option.
  DDraw   DirectDraw is a video control standard under Windows 95. If
          your VGA card supports DirectDraw, please select this option.
  WinG    WinG is a fast displaying standard under Windows 3.1. By using
          WinG, the picture quality is worse and the performance is
          lower comparing to those of DCI or DirectDraw.
  GDI     GDI is a display standard under Windows 3.1 and Windows 95
          which achieves the worst performance among the four methods.

Q&A:

  Q:      While playing VCD under Windows 95, the speed is very slow and
          the audio is break into segments. Why?
  A:      Most of these situations are caused by the conflict of IDE
          devices which connected to the same IDE bus. Your computer may
          be equipped with one IDE hard-disk and one IDE CD-ROM drive
          and these two devices are connected to the same IDE cable.
          There is a bug in Window 95 to handle such a situation. The
          CD-ROM driver provided by Windows 95 dumbly tries to issue
          seek command on every CD-ROM read request. It slows down the
          performance. There are two ways to solve this problem: one is
          to ask the technician to move one IDE device to another IDE
          cable; the other is to download 'iosupd.exe' from Microsoft
          ftp site and execute it. This is a patch program for the
          CD-ROM device driver.

  Q:      VCD PowerPlayer cannot play CD-I under Windows 95, why?
  A:      Windows 95 Compact Disc File System (CDFS) does not support
          CD-I format such that LinkMPEG can not read the data on the
          CD-I disc.

  Q:      Why can't I execute VCD PowerPlayer under 16 color display mode?
  A:      Most of VGA cards do not support DCI (DirectDraw) under 16
          color mode, and VCD PowerPlayer does not support GDI and WinG
	  display under 16 color mode either. Please change display mode
	  to 256 color or higher.

  Q:      VCD PowerPlayer can not use DCI (DirectDraw) under hi-color
          display mode or hi-resolution display mode, why?
  A:      Under hi-color display mode or hi-resolution display mode, the
          display occupies most of the display memory (which is on the
          VGA card). Such that there is not enough display memory to be
          used while using DCI (DirectDraw) functions. Then, DCI
          (DirectDraw) is turned off. Please set it to low color display
          mode (e.g. 256 color) or low resolution mode (e.g. 800x600).
          Another way to solve this problem is to expand the display
          memory on your VGA card.
