SYMPTOMS
When you play a multi-bit rate .asf file from a Web server, the video may not play, even though the audio does.



CAUSE
Generally, Web servers only stream files to a Windows Media Player client. The client is not able to select a video stream for a multi-bit rate .asf file.



RESOLUTION
Put the multi-bit rate file on a Windows Media Server. A Windows Media Server is designed to select the appropriate video in a multi-bit rate .asf file.



MORE INFORMATION
The Windows Media Encoder can encode multiple bit rate .asf files so that clients with varying speeds of Internet connections can automatically select a band of video that closely matches their connection speed. The Windows Media Player and Windows Media Server negotiate the appropriate video band to be sent to the client based on connection speed. Web servers cannot determine this bandwidth negotiation.

If you are creating content that will be placed on a Web server, do not create a multi-bit rate .asf file.
