Video for Windows 1.1--Automatic Window Shift Problem

ID: Q118390

The information in this article applies to:

Microsoft Win32 Software Development Kit (SDK), versions 3.1, 4.0

When a video playback window is created using MCI, the Video for Windows (VfW) system software may shift the window a small distance vertically or horizontally from the original location.

The video software does this to align the window on even-byte boundaries in video memory for optimal playback speed. When the window is located on a byte boundary, the video software is not required to perform bit-intensive calculations during video playback, increasing the playback speed.

This behavior is particular to Video for Windows and cannot be controlled by the application being affected.
