The slide show length does not match the song length when you use the Change slide show length to match music length option in Windows Vista

Slide Show Length does not Match Song Length

You use serveral 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).

To work around this problem, use song files that are not encoded with a VBR.

This problem occurs because the lengths of the MP3 files that are encoded with a VBR are not correctly detected when you create the slide show.
