1. Overview
This disk (or CD-ROM subdirectory) contains the ELSAmotion
Windows driver and the setup utility for installation.
The Windows driver enables the ELSAmotion to be used as an
MCI-device by Windows Media-Player and alikes. It can be
used to view MPEG films under all graphics modes your graphics
card supports. MPEG films may be taken from CD-ROM, VideoCD or
CD-i (CD-interactive) devices. Playback may be done with up to
30 frames per second from iconic size to full screen (depending
on your graphics board). For this, a DCI-/DirectDraw- supporting
graphics board is required (e.g. ELSA WINNER 1000AVI, WINNER 2000AVI,
WINNER 2000PRO/X..).
SETUP is an installation program for the installation and
configuration of the ELSAmotion Windows driver.
------------------------------------------------------------------------
2. Disk contents

directory) to your harddisk, because there are some changes
required in your SYSTEM.INI and WIN.INI, too.

------------------------------------------------------------------------
3.1 Installation Windows 3.1x
Prior to installation of ELSAmotion, an DCI-capable graphics
board (and its drivers) as well as Video for Windows 1.1d (or
newer) from the ELSA CD have to be installed. ELSAmotion has to
be inserted into a PCI-slot that is capable of running as a
"PCI-BUSMASTER" (see documentation of your PC).
You can install the ELSAmotion Windows driver with the
program SETUP.EXE on this disk "ELSAmotion Driver for
Windows 3.1x" or on CD ROM in the subdirectory labeled
"MOTION".
Start Windows, call in the "Program Manager" "File"/"Run ...",
enter the commandline "a:setup" (or the appropiate directory
if you install from the ELSA-CD) and confirm with "OK".
SETUP asks for your language, installs the ELSAmotion Windows
driver and modifies your SYSTEM.INI and WIN.INI files
accordingly. If asked, please insert the disc labeled "MPEGtest"
into your disc-drive.
3.2 Installation Windows 95
You may install ELSAmotion for Windows 95 as you do with
Windows 3.1x. If you insert ELSAmotion for the first time
into your computer, you are asked to use the Windows 95
standard installation path, which is also possible.
Fullscreen replay is only possible with DirectDraw and offscreen
memory. Also, there may be a need to install DirectX (Direct Draw,
Direct Sound, Direct Play) to your system. If you use Setup, you
will be prompted to install DirectX if it hasn't been before. If
you used Windows 95 procedures for ELSAmotion installation, you
won't see ELSAmotion drivers in the "Devices" of Media Player.
Direct Draw resides on an extra disc (labelled "DirectX") or in
the directory "\ELSAWARE\DDRAW" on CD Versions. To install
DirectX, change to the subdirectory "DirectX" and start the
program "Dxsetup.exe".
CAUTION:
after installation of DirectX from CD, you will have to
reactivate your WINNER driver if you own a ELSA Graphics Card.
This is due to the fact, that Microsoft DirectX reinstalls
original S3 drivers.

5. Caveats
This section documents known anomalies or problems and gives
hints on work arounds.
5.1 Installation
Installation problems may be checked out in detail by
"MPEGTest". See documentation.
If the Media Player encounters any problems with an MCI-device
(e.g. board removed..) after changes in SYSTEM.INI it marks the
device as bad and removes it from his device-table. To reenable
it, you have to remove the lines "MPEGVideo=0," and "VideoCD=0,"
from the MPLAYER.INI file or modify SYTEM.INI again and restart
the Media Player without a mpeg-film file name. In Windows 95,
the driver is checked at every start of MediaPlayer.
If there were other MPEG-devices installed, their dynalinks are
removed, but they remain accessible as MCI-devices.
5.2 Using VideoCD / CD-i
Depending on an alternate data format, CD-i's are unreadable by
some CD-ROM drives. See section 5.11 for details on certain
drives. If you get a message "MCI device not installed" using
the VideoCD driver and having inserted a VideoCD in your drive,
your CD-ROM driver isn't capable of reading "raw-mode" (2532
bytes per sector, no error correction). An updated version
should solve the problem.
If you try to replay pure CD-i's, tracks may not appear. Linear
replay and positioning by time/frame are possible.
5.3 Distortion of sound / Framesize
Depending on Framesize there might be short flaws in sound
(mainly in "primary" mode on slower graphics boards). For this
reason frame size in the above mode is limited to 800*600 dots.
If film stops sometimes for a short while, you should disable
your disk-cache (e.g. smartdrive) for the drive you play your
mpeg files from.
Replay speed is settable to 1 (speed 1000) or 2 (speed 2000),
but, in double speed mode, frames are dropped.
5.4 Supported graphic boards / color modes
Recently there are color failures in 24 bpp mode and in
YUV. Using "offscreen" they aren't used. Using 8 bpp modes may
lead to false colors on the desktop, which will be restored
after closing media player. Try setting up Windows Desktop to
use "Windows standard color scheme" if color is mismatched.
Current hardware / software doesn't support 64k-banked VGA as
well as scattered "offscreen"-surfaces. In this case your
graphics cards isn't able to deliver graphics memory "in one
piece". These errors will be solved by future hardware releases.
5.5 Other caveats
- Copy / Capture sometimes leads to system hangs.
- Depending on MPEG coding, some films can show distorted,
interrupted video. This won't happen with professional CD-i's
or VideoCD's.
- "Cue to" without the "noshow" flag sometimes crashes the driver
5.6 Triton Board failure / 486-er PC's
On some of the newer Pentium boards with the Triton Chipset
(mainly Intel Alladin and Zappa) the system crashes after a
few seconds running offscreen. The reason is a bug in the chipset
which may be circumvented by reprogramming it. This is enabled
automatically, but can be disabled by inserting "TritonFix=0" into
the [DCISurface] section of "win.ini" (Win31) or in Registry's
section "HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/
Class/MEDIA/DDrawSurface" (Win95).
If you encounter other crashes, especially corrupting harddisk,
you will need to disable IDE prefetch buffer in the BIOS. This
is due to a bug in your IDE controller chip in conjunction with
the Triton Chipset.
5.7 not supported MCI-commands / parameters
- seek parameter exactly
- only audio and video stream 1 is supported
- no frame-exact positioning
- step parameter key not supported
5.8 OLE-embedding
there is no still frame displayed
5.9 Windows 95
Some of the Win95 CD-ROM-drivers aren't capable of reading CD-i
inspite of their Win 3.1x counterparts causing no problems. Also,
on some drives swapping VideoCD's will not be recognised. Close
Mediaplayer and start it again.
ELSAmotion is only capable of running offscreen if used in
conjunction with DirectDraw. On ELSA WINNER graphics boards,
Windows 95 driver Version 1.04 and newer is required. If you use
it with other graphics boards or older driver versions, you will
only have DD-primary support. The same will appear, if you
upgrade from Windows 3.1x to Windows 95 without reinstalling
ELSAmotion driver. On 2MB cards DirectDraw will only run off-
screen up to 800*600 pixels with 16 bpp. Future ELSA WINNER
drivers will fix this.
If you install ELSAmotion and ELSAvision boards in parallel, the
software starting later will have access to primary surface only.
Newer releases of ELSAvision software will stop this.
5.10 Low DOS memory
If you encounter the message: "No memory for CD-ROM data buffer"
(or "...control buffer") while starting MPEG or VideoCD driver,
you are out of DOS-low-memory. This memory is required for
reading of VideoCD and CD-i. If you don't plan to play "*.DAT"-
files directly (single tracks of VideoCD), you may suppress this
message by inserting the line: "VideoCDFiles=0" into
[ELSAmotion] section of "elsamot.ini". On Win95 systems, these
effects are unlikely to happen.
5.11 Compatibility of CD-ROM's
The following combinations of CDRom-drive / Controller / driver
are known to work:
- Win 3.11
Sony CD33
Sony CD55 / ATAPI / IDE
Toshiba 3601 & 3701/ Adaptec 2940 & NCR / EZSCSI 4.0c
NEC 6xi / NCR / adaptec drivers
Toshiba 5302B / IDE
Plextor 4PlexPlus / Adaptec AVA-1505 / Aspi2Dos 3.59, Aspicd 3.2
- Win 95
Toshiba 3501 / NCR / with DOSCAM, ASPI, ASPICD (from adaptec)
Toshiba 3501 / Adaptec / ASPI8DOS V1.12, ASPICD
Toshiba 3401 / NCR
Toshiba 3701 / Adaptec 2940 / EZSCSI 4.0c no CD-i replay
5.12 Coding of Audio Files
Because ELSAmotion does a lot of buffering, the correct end-of-
file is hard to recognize on short Audio-only MPEG's. If you are
a producer of this type of file, include about half a second of
silence after your audio.
