Audio out of sync on final movie only

[Geneva]

I created a movie consisting of pictures and video. The video clips are of
varying resolutions and file formats. Most of the video has audio tracks. I
added a sound track to the video using the Audio/Music track.

When editing and viewing the movie within Movie Maker, the video images sync
up with the lyrics in the music track exactly as I set them. All is well
here.

Then I create the movie file. The video images are now showing later than
expected. In other words, the lyrics are earlier than the associated image.
When I go back to the movie project, it runs exactly like I originally set it.

Any ideas to help me out here?

Are you using VBR MP3s?

If so convert them to WMA or Wav or CBR MP3.
