NOTES TO WINDOWS 95 USERS
*************************************************************************

** XingMPEG Player 2.0 for Windows95 is now available!                 **
** Read "XingMPEG Support" at the end of this file for information     **
** about obtaining an update.                                          **

REGARDING VIDEO ACCELERATION AVAILABILITY - Under Windows95, DCI
acceleration is unavailable with most Display Systems. If you are
using such a display system, you must obtain a Direct Draw version
of the XingMPEG Player and Direct Draw drivers for your PC's Display
System to access video acceleration (including hardware stretching
and color space conversion). Read the "XingMPEG Support" at the end of
this file for more information.

REGARDING PLAYBACK OF CD-I TITLES - If you encounter problems playing
CD-i titles (or Video CD titles opened with the "Open CD-i Movie"
command) read the "Xing Tech Note" later in this file for more

*************************************************************************
RELEASE NOTES TO XingMPEG Player VERSION 1.2
*************************************************************************
XingMPEG Driver (XMDRIVER.DRV)
- The XingMPEG Driver's configuration dialog contains a new audio
  sampling rate option "44kHz".
- The XingMPEG Driver now supports a wider selection of CD-i titles.
- The XingMPEG Driver now handles changes in frame resolution when
  playing multiple tracks from a CDi or Video CD title.
- Handling of on-the-fly switch from DIB to Primary Surface DCI has
  been improved.
- Handling of on-the-fly resizing of a non-DCI video window
  under Windows 95 has been improved.
- The XingMPEG Driver now properly accesses primary DCI surfaces
  when opened as a child of an application's window.
- Corrections have been made to the return values of several MCI
  commands. 
- The XingMPEG Driver now returns "1.2" when responding to the MCI
  command "INFO VERSION".

XingMPEG Player (XMPLAYER.EXE)
- The XingMPEG Player’s Standard Bar and Advanced Bar display modes are
  now unavailable under Windows 95.
- Clicking the "Step" buttons during playback now stops playback.

*************************************************************************
RELEASE NOTES TO XingMPEG Player VERSION 1.1
*************************************************************************
XingMPEG Driver (XMDRIVER.DRV)
- Installation of the XingMPEG Driver now registers two MCI device TYPES:
  In addition to the "MpegVideo" device type, the device type "CDIVideo"
  is registered to provide direct access to CD-i and VideoCD titles.
- The XingMPEG Driver's configuration dialog contains a new option
  "Crop to fit in standard window" that affects the driver's behavior
  when playing CD-i movies. When this option is selected, CD-i movies
  whose horizontal dimension is greater than 352 pixels are cropped
  to fit in the standard 352 pixel wide Video Display window.
  This feature is provided because some DCI-compliant Windows display
  systems suffer degraded video playback performance when video frames'
  horizontal dimension exceed 352 pixels. If you notice slower video
  playback when playing CD-i titles, try enabling this feature.
- The XingMPEG Driver now returns "1.1" when responding to the MCI
  command "INFO VERSION".

XingMPEG Player (XMPLAYER.EXE)
- The XingMPEG Player’s "File" menu now contains the entry "Open CD-i 
  Movie". When this item is chosen, the XingMPEG Player automatically 
  locates and opens all readable MPEG files on a mounted CD-i or VideoCD
  disk.
- The File Information window’s "File Duration" field now displays the
  correct SMPTE formatted value; previously, calculation of this value
  failed to account for the loaded file’s frame rate and assumed
  30 frames/second.
- Clicking on the Track Bar now moves the current position indicator
  in increments equal to approximately 1/16 the total duration of
  the current file. In previous versions, clicking on the Track Bar
  moved the current position indicator in 1 second increments.

*************************************************************************
RELEASE NOTES TO XingMPEG Player VERSION 1.03
*************************************************************************
XingMPEG Driver (XMDRIVER.DRV)
- The XingMPEG Driver now returns "1.03" when responding to the MCI
  command "INFO VERSION".
- Eliminated an unnecessary reinstallation of the color pallette (in
  256 color display mode) that occurred when the XingMPEG Driver switched
  between DCI and DIB during video playback.

* Note Regarding Unreadable MPEG Files:
  The XingMPEG Player can play any MPEG file that conforms to the MPEG-1
  standard. Some MPEG files do not conform to this standard; e.g., they may
  have undergone data encryption that renders them readable only by the
  application that performed the encryption; or they may contain non-standard
  data. If you attempt to play such an MPEG file with the XingMPEG Player,
  an error message appears indicating that the file is unreadable.

*************************************************************************
RELEASE NOTES TO XingMPEG Player VERSION 1.02
*************************************************************************

XingMPEG Player (XMPLAYER.EXE)
- The "Rate Control Off" warning is re-enabled whenever the driver's
  Rate Control setting is toggled.

XingMPEG Driver (XMDRIVER.DRV)
- The XingMPEG Driver now returns "1.02" when responding to the MCI
  command "INFO VERSION".
- Corrected method for sending a null region to DCI providers;
  prior to this change, clipping the video window occasionally
  produced unwanted remnants of the DCI surface.
- Eliminated an unnecessary yield on Show Window call; prior to this
  change, some applications (e.g., video screen savers) might destroy
  the video window prior to closing the MCI driver instance.
- Improved handling of bad data in an MPEG stream; prior to this change,
  corrupted data in an MPEG stream could cause cessation of video playback.
- Eliminated problem whereby the Performance diagnostic failed to play
  video in some 256-color display environments; this change also
  eliminated potential playback problem when an MPEG file is passed to
  XMPLAYER as a command line argument.

*************************************************************************
RELEASE NOTES TO XingMPEG Player VERSION 1.01

Title		Windows 95 and GreenBook CDi Titles
Catalog#	W9500010
History		created 8/2/95 by tsilva
		modified 8/30/95 by saiena
		modified 11/21/95 by saiena

**********************************************************************

Windows95 uses a new interface (CDFS) to CD-ROM device drivers.
Because CDFS does not support Greenbook CD-i "Digital Video" disks,
such disks are currently unplayable under Windows95; WhiteBook CD-i
"VideoCD" disks are however supported. If, when attempting to play
MPEG data from a CD disk, your PC produces an error message
(e.g., "no CD" or "CD not ISO-9660 or High-Sierra compatible"),
you likely have a GreenBook CD-i title.

Because the XingMPEG Player version 1.3 supports the older MSCDEX
interface to CD-ROM devices, it may be possible play GreenBook titles
by reconfiguring your PC to use MSCDEX instead of CDFS; BUT there
are some considerations:
- MSCDEX is slower than CDFS;
- because the CD-ROM driver must be loaded in REAL mode, system
  performance is slightly slowed;
- some CD-ROM drivers/drives may not work with GreenBook CD-i titles
  even after the reconfiguration; replacement of the CD-ROM driver/drive
  may be necessary to enable playback of GreenBook titles;
- There may be other ill effects of which we are currently unaware.

*  DISCLAIMER:
*  Because of these considerations, we strongly recommend that you
*  back-up your PC's file system prior to performing the reconfiguration.
*  
*  The procedure described in this file is not guaranteed to enable
*  GreenBook and WhiteBook CD playback on all PCs.

**********************************************************************
To enable reading of GreenBook CDi titles from within Windows 95, complete
the following steps (you must have a properly functioning CD in
your PC before completing these steps):

- Type the CONFIG.SYS file on the root of your Windows 95 boot drive,
  and note the line that loads your PC's CD-ROM driver; e.g., the
  following command types the config.sys file:
    type c:\config.sys
  And the following line loads the CD-ROM driver:
    DEVICE=C:\UTILS\SCSI\ASPICD.SYS /D:ASPICD0
- Edit the AUTOEXEC.BAT file on the root of your Windows 95 boot drive,
  and add a line that loads the MSCDEX program, e.g.:
    <PATH>MSCDEX.EXE /D:<DRIVER>
  Where <PATH> is the path to the MSCDEX program,
  and <DRIVER> is the name of the driver specified in your PC's
  CONFIG.SYS file, e.g.:
    C:\WINDOWS\COMMAND\MSCDEX.EXE /D:ASPICD0
- Edit the IOS.INI in your PC's Windows 95 directory, and find 
  the line that specifies your PC's CD-ROM driver, e.g.:
    aspicd.sys	; adaptec PM driver exists
  If this line appears in the [SafeList] section of the file, move it from
  the [SafeList] section to the [CDUnsafe] section; e.g.: after you move
  the line, your IOS.INI file should have lines that look like this:
    [CDUnsafe]
    aspicd.sys	; adaptec PM driver exists
- Reboot your PC.

At this point, if problems persist, try diabling 32-bit disk access:
- Run the SYSTEM control panel
- Go to the PERFORMANCE panel
- Click the "File System" button
- Go to the "Troubleshooting" panel
- Enable the option: "Disable all 32-bit Protect Mode Disk Drivers"
- Reboot your PC
