adapter. If you do not have one, contact your video adapter
manufacturer.
MICROSOFT WINDOWS NT INFORMATION
================================
The Motion Pixels player is not currently supported under Windows NT.
MICROSOFT WINDOWS 95 INFORMATION
================================
SCREEN SAVERS: We have observed that screen savers will interrupt video
playback. To prevent this, disable your screen saver.
VIDEO and NETWORKS: We have observed that network support can cause
frequent system pauses. If your video playback pauses, disabling
network support should correct this problem.
TROUBLESHOOTING
===============
DIAMOND DRIVER PROBLEM WITH S3 VIDEO CHIPSET. At the end of the MVI
video clip, the computer will hang, or give an EMM386 error, or the next
time you press the play button it will hang the computer. There is a
bug in the Diamond Windows driver which can be solved in either two
ways. Use the Number Nine S3 video drivers or upgrade Windows 3.x to
Windows 95.
INCOMPATIBLE RAM DAC. Some video chipsets and video BIOS's support 32k
colors, but the RAM DAC does not. The video will play in the correct
size but the colors will not be correct. The user must upgrade the RAM
DAC or play the video in a pallettized mode, or upgrade the video card.
VIDEO HANGS FOR NO REASON UNDER WINDOWS 95. An internal memory
corruption has occurred in the video source. Microsoft has indicated
that they have seen this problem before, and relate it to a hardware
condition.
INCOMPATIBLE HERCULES DRIVER. Hercules drivers for the Dynamite ET4000
video chipset at 640x480 16 colors, will start the display memory at
page four. No video will be seen. Upgrade the video drivers, or
upgrade to Windows 95.
INCOMPATIBLE ATI MACH64 BIOS. Trying to play the MVI video will result
in an internal Windows error. The ATI Mach64 BIOS will generate a page
fault setting the video mode in protected mode under Windows 3.x.
Upgrade to Windows 95.
I/O PORT CONFLICT UNDER WINDOWS. A sound driver under Windows has full
control of the I/O port, and will not share it with any other VM
machine. Disable the driver, usually the midi SAPI drivers or upgrade
the driver to one that supports virtual I/O sharing.
PAUSES DURING VIDEO PLAYBACK UNDER WINDOWS 95. Windows 95 has a
resource sharing problem. Disable virtual memory under
System/Performance/Virtual Memory.
CANNOT LOCK MEMORY USING QEMM 7.04. Qemm DPMI has a bug for addressing
physical memory above the DPMI's host memory. Upgrade Qemm to version
7.5, or Windows 95.
VIDEO DOES NOT PLAY. Disable the 32bit disk and file access under
virtual memory settings, or upgrade to Windows 95.
AUDIO HAS PAUSES DURING PLAYBACK. If Motion Pixels is using 4bit ADPCM
compressed sound, some sound blaster compatible cards are not true
compatibles. Install a new sound card or play the video with no sound.
VIDEO HANGS DURING MVI PLAYBACK when the Windows 95 screen saver kicks
in. Disable the Windows 95 screen saver.
USING MICOSOFT PLUS 95 with the show full window drag option, it leaves
trails behind in Video For Windows. This is a Video for Windows
problem. Disable show full window drags in Display/Plus.
