When you stream files from a Windows Media Services 9 Series server, you may notice a delay of 5 or 6 seconds when you switch between files. This wait may be an undesireable user experience.
This problem occurs because of the way the Windows Media Player 9 Series server submits the client rendering log to the Windows Media Services 9 Series server. When the server is set up to accept client rendering logs, an internal error may be incorrectly reported on the client when the client waits for a response from the server. If this behavior occurs, the client times out after a default period and then opens the next file. In this case, the server receives the correct log from the client.
