I can't remember off hand if it was playing in the preview. I'm assuming it was or I wouldn't have tried to burn it. I tried adding text and a title to a new track but couldn't figure it out. I originally clicked directly on the image on the time line and added my title....but that obiously didn 't work.

That could be the problem - look in the pdf manual installed with the software under the section called Title. This has pretty comprehensive instructions explaining the process of adding a title (it is too long to put here as there are so many ways).
