Analog Overlay WDM Drivers Do Not Work with DirectShow

ID: Q230766

The information in this article applies to:

SYMPTOMS

DirectShow programs may not provide playback when they are used with analog overlay DVD hardware supported by Windows Driver Model (WDM) drivers.

This problem is known to occur in conjunction with the Creative PC-DVD Encore Dxr2 DVD-ROM system.

The problem affects DVDPlay, Microsoft Encarta 99, anything using Microsoft Internet Explorer 5 and Microsoft Windows Media Player 6.1 for DVD playback, any DVD video player program using DirectShow, and any DVD-ROM or DVD video title using DirectShow.


CAUSE

The implementation of DirectShow provided with the products listed above cannot provide WDM drivers with chroma key information during calibration. As a result, WDM drivers cannot show video.

MORE INFORMATION

The third-party products discussed here are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.

Unlike digital solutions, analog overlay technology does not require a compatible feature connector on the video adapter. Analog overlay places decoded MPEG-2 images on top of a key color in the video adapter output, and sends the composite to the monitor. The video image can bleed into windows that inadvertently use this key color.
