Audio Sync problem burning to DVD

I have a video with separate audio and video tracks. Namely the problem is with a series of still images shown at the beginning. On my computer they sync perfectly with the music, but once I burn it to a disc everything goes to ****. How do I keep the video and audio going at the same pace?
 
If you are running XP, run Windows Movie Maker (Start>Search and search for Windows Movie Maker in All Files and Folder.) Then put on the video/images, and insert the music to the timeline, then save as a new movie file, and burn that.
