Consider the following scenario:

• You use several pictures to create a Windows DVD Maker slide show in Windows Vista.
• You use the Change slide show length to match music length option together with several song files.
• One or more of the song files are MP3 files that are encoded with a variable bit rate (VBR).

In this scenario, you find that the slide show length does not match the song length. Therefore, there are sections of silence between the songs.
