Saving movie onto CD or DVD

[Guest]

I am getting an error message when I try to save my movie to CD or DVD. It
says "This project contains source files that are missing or that have been
modified after import. Your project cannot be saved as a movie until the
source files have been located or deleted from the project." What should I do
here? I have not modified any of my files. I did however create the idividual
clips in photostory first and then imported them into movie maker to create
the movie. Please help! I have been trying to save this file for 2 days now.

Usually this is due to a compatibility problem but if ALL your source files
are imported from PS3 then they are compatible.
Are there ANY files in the project that are not from PS3 (such as audio or
images)?
If so what types (extensions) are they?

Are there any red X's in the timeline indicating that Movie Maker can't find
the file in the specified location?
If so then right click and click "Browse for missing files..." then find
them.

How long is the project (# of clips, transitions / length in minutes)?
It could be the project is too complex which can be fixed by splitting it
into pieces (see my website for a step-by-step)
