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

This update to Video for Windows 1.1 provides improved palette
support, DCI support and overall improvements in performance.

1. PALETTE SUPPORT
=====================

Video for Windows has always allowed the application to select
a specific palette for playback on 8 bit displays.  Unfortunately, 
the codecs (compressor\decompressors) were never aware of this 
palette request.  Instead the codecs would dither to their own 
standard palette.  Video for Windows would then further dither 
the video to the requested color palette.  The net result was 24 
bit videos, when played back with a requested palette, were 
dithered twice.  This would compromise the quality of the video.  

This problem has been solved with this new drop of MSVIDEO.DLL, 
and the Cinepak and Indeo codecs.  The codecs will now decompress 
directly to a requested palette.  You can request the codecs to use 
a palette with either the SETVIDEO <alias> PALETTE HANDLE TO <hpal>, 
or REALIZE <alias> BACKGROUND MCI commands.  You can find these 
commands in the Video for Windows 1.1 documentation.

2. DCI SUPPORT
=====================

DCI allows Video for Windows to take advantage of the enhanced 
capabilities of your display cards.  You will now see faster and 
smoother playback of video on display cards whose drivers support 
DCI .  Furthermore, the performance of stretched and clipped 
videos will be drastically improved for all displays.
