This Sampler Disc has been created using the Macromedia Director
(TM) Player for Windows, and this in turn relies on Apple Computer's
QuickTime(TM) for Windows to deliver the video parts of the
sampler product. 
The following is technical support information supplied by Apple Computer
that may offer assistance should you encounter problems in running the video sequences
built into this sampler product.

PC AUDIO CARD COMPATIBILITY
The following chart summarizes the audio hardware products 
that were tested with QuickTime for Windows 1.1.
Most compatibility issues are based on driver versions.  
With some boards, more than one driver was tested. In most cases,
the latest available driver was tested.
THE DRIVER TESTED MAY NOT BE THE SAME VERSION AS THAT WHICH 
CAME WITH THE AUDIO CARD.  Contact the vendor for the latest 
driver version.  Known bugs are included.

The information is provided in the following format and is delimited by tabs:

Manufacturer	Model	Bit Depth	Stereo	Driver	Version
Problems


Creative Labs	SoundBlaster Pro	8	yes	SBPSND.DRV	5/15/92 11:12
This driver has a known problem that affects both QuickTime for Windows
and Microsoft Video for Windows. When sound samples less than 2k are played,
the card may play 1/4 second of sound repeatedly for about 5 seconds. This can be 
triggered by any QuickTime movie, or simulated by clicking to and from two playing
Movies in the Movie Player.

Audio sticks because of a driver problem. Problems with sound in loop appears only
in the driver which currently ships with the board. Previous and subsequent driver 
releases do not exhibit the problem.

PC VIDEO CARD COMPATIBILITY
The following chart summarizes the video display cards that were tested with QuickTime
for Windows 1.1.  Most compatibility issues are based on driver versions. 
With some boards, more than 1 driver was tested. In most cases the latest available 
driver was tested.  THE DRIVER TESTED OR SUPPORTED MAY NOT BE THE SAME VERSION 
AS THAT WHICH CAME WITH THE VIDEO CARD. Contact the vendor for the latest driver version.  Known bugs are included.  For Pixel Depth : 8 bits = 256 colors, 15 bits = 32,768,  16 bits = 65, 536 and 24 bits is 16 million colors.

If your video card is not listed below and you are having SEVERE compatibility problems,
you may consider modifying the QTW.INI file. Change the [Video] setting to 
Optimize = Driver.  This may resolve severe compatibility problems with a specific
video card but will also reduce the performance of Movie playback.
See MODIFYING QTW.INI FOR COMPATIBILITY.

MODIFYING QTW.INI FOR COMPATIBILITY
NOTE:  Modification of the QTW.INI file should be done at your own risk.
Typically one does not need to make any modifications to this file.  For some 
compatibility issues, modifying the file will make video or audio cards work properly, 
but with reduced performance. Be sure to make a backup of the QTW.INI file before 
modifying it.

The most common modification to the QTW.INI is to change the [Video] setting to 
Optimize = Driver.  This may resolve severe compatibility problems with a specific 
video card but will also reduce the performance of Movie playback.

Once, again modify at your own risk.

[Video] (in order of priority)
Optimize = 	Hardware (default) 
		Driver
		BMP
		RAW
		DIB

[Video Optimize]
This is not used

[Override] // group
DREF = no or yes {NO forces QTW to use the file as self referencing, useful for 
QT 1.0 files}

[Data Handler]
CDROM Xfer Rate* = [integer] ranges from 100 to 600, where number is in K, default 
is 328.
CDROM Seek TIme* [integer from 0 to X] where x is 100 to 350 in ms for average seek, 
default is 200.
CDROM Block Size = [integer, expressed in K] default is 8, range is 1 to 64.

Max Open Files =[integer] default is 64.
Max Consumers = [integer] usually same as Max Open Files. You can have multiple 
consumers per file.
Max Cache Size = [integer] expressed in K, default is 128, ranges from 64 to 512.

Disk Xfer Rate = [integer] same as CDROM Xfer Rate, default is 300.
Disk Seek TIme [integer] expressed in millisecon s per average seek, defgault is 35.
Disk Block Size = [integer, expressed in K] default is 16, range is 1 to 64.

Network Xfer Rate = [integer] same as CDROM Xfer Rate, defalut is 250
Network Seek TIme [integer] expressed in millisecon s per average seek, default is 40.
Network Block Size = [integer, expressed in K] default is 16, range is 1 to 64.

Floppy Xfer Rate = [integer] same as CDROM Xfer Rate, default is 18.
Floppy Seek TIme [integer] expressed in millisecon s per average seek, default is 100.
Floppy Block Size = [integer, expressed in K] default is 2, range is 1 to 64.

[Sound]
Requested Rate = [integer] ranging from 5000 to 44000 (has to be exact rate for 
MPC cards)
Actual Rate = same possible rates as requested

* Set dynamically by QuickTime for Windows, based on what it senses as the CD-ROM speed.
