Notes

• The Windows Media Playlist Editor is only available in the Windows Media Services snap-in.
• Content streamed by Windows Media Services must meet the minimum supported content length of the player to ensure reliable playback. The minimum supported content length for Windows Media Player 9 Series or later is 5 seconds. The minimum supported content length for previous versions of Windows Media Player is 30 seconds.
• If your playlist includes JPEG image files, do not include any syntax in your playlist that causes the image to pause while being rendered by the player. Pausing a JPEG image in this manner can cause the player to enter a permanent wait state. If you must show a still image under these circumstances, create a video file of that image and then use the video file in the playlist instead.
• If your playlist includes JPEG image files and you are using the playlist file with a broadcast publishing point, be aware that users who connect to the broadcast while the JPEG image is being streamed will not receive the image. They will instead see a black screen. Once the playlist continues on to the next item, playback will continue as expected. If you want a JPEG image to be displayed for a certain period of time, you should use the repeatCount attribute to repeat the image for short durations that together equal the amount of time that the image is to be displayed. That way, players that connect while the image is being streamed can receive the image when it repeats. For example, if a JPEG image is to be displayed for 60 seconds, you could set a dur attribute value of five seconds and a repeatCount attribute value of 12. If a user connects two seconds into the broadcast, the image would be displayed after three seconds. If the repeatCount and dur attribute values were not used, the user would see a black screen for 58 seconds.
