SUMMARY
When you use a .asx file as a play list to stream multiple .asf files from a Windows Media server, the Windows Media Player buffers before playing each clip. To make the switch between clips smoother, you can add an event in the .asx file so that the player pre-buffers the next clip before finishing the first clip.



MORE INFORMATION
The  tag can be used to trigger pre-buffering of a clip. For example:   

 

   In this example, the EVENT NAME is a required field, but can be named anything you choose.

Some buffering may still occur between clips, but the buffering time should be reduced.

If the first clip is a lower bit rate than the second clip, the pre-buffering time is longer. This is because the initial buffering of the second clip is done at the bit rate of the first clip. If the bit rates of the clips are the same, the buffering time should be short.

NOTE: This sample does not work for Windows Media Player 7.

For more information on .asx files see the Windows Media Player SDK. This can be downloaded from the following location:
