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.
