The following information applies to Microsoft Video for Windows,
version 1.1d.

Introduction
------------

This Application Note includes a floppy disk containing a run-time
edition of Microsoft Video version 2.0 for Windows. This maintenance
release provides the following improvements and corrections to the
previous version, 1.1a:

 - Improved palette support. The new release of MSVIDEO.DLL and the
   Cinepak and Indeo codecs prevent Video for Windows from having to
   dither 24-bit videos twice during playback.

 - Display Control Interface (DCI) support. DCI allows Video for
   Windows to provide faster and smoother playback on video cards that
   use the S3, Cirrus Logic, or any one of several other chip sets.
   Video for Windows now also supports all DCI-enabled video cards.
   Furthermore, the performance of stretched and clipped videos is
   much improved for all video cards.

 - Better overall performance.

The improvements implemented in version 1.1a are listed in the section
"Previous Improvements in Version 1.1a" on page 2 of this Application
Note.
