iphoto Problems

Hi everyone. Im using a Macbook 1.83 ghz and theres a problem with iphoto. How come whenever i try to "share" my slideshow and send it to idvd it says "An error occured creating movie file: Export movie file could not be created." Ive tried putting 100 pictures, 1 picture, music, no music, but nothing works. Any ideas?

I figured it out.

It would be nice if you posted the 'fix' for others to see....someone may be stuck with the same problem....
