QA Notes:
-HW MPEG and VPM have been tested only in Sigma Design's REALMagic in a

Known Problems
==============
-In Windows 95, lines appear across the video window when it is moved
around the screen. PDR#5096
-With panning on, changing video color using Color Correction utility revert
color back to default as soon as you pan/scroll the screen. PDR#8037
-If you are running any Direct Draw game modes that is lower than 640x480
(ie. 640x400), display switching via hot key causes screen corruption.
The switching should be blocked as in 7548 products.
Drivers limitation
===================
-If you put something on top of the HW video MPEG playback, the playback
image underneath would be transparen. This is not a problem.
-Some DirectX games cause noise in 400x300x16 mode. PDR#7613
-A black horizontal line flashes across the scren when choose LCD or LCD/CRT
option in Monitor Refresh utility. PDR#5426
-Color Correction that controls the video playback would not work when MVA is
disabled (eg. Video playback in 640x480 resolution in Windows desktop with
800x600 panel because the BIOS default these modes to expansion-on to cover
the entire panel screen. As per spec., when expansion is on, MVA is
disabled).
-In 1024x768 modes, only 60Hz vertical refresh rate can enable MVA. Any other
vert. refresh rate would turn on MVA therefore Color Correction for video
would have no effect.
-If you are playing video clips and what to change resolution or color depth,
it is recommended to stop the playback first else you would see unpredictable
result.
-When switch to TV with AITech external TV implementation and the TV screen
can not display all image, contact AITech International, Inc. for utility
to correct this problem.
