Slideshow Maker In Linux Environment

Dear all,
I want to create a slideshow.
I tried SMILE, which seemed easy to use with many features.
But I cannot save the project as an avi- or mpeg-file anymore.
It worked fine at the first time, so I do have a one avi- and one
mpeg-file. But I worked on on the project, I can select to render
the project and the system will work hard for a while

  • but there is no new avi- or mpeg-file.
    Any hints?
