yes, I've tried all options.. including export all files, and another one "export all resources, including dependences".
I've have noticed that a file called "data.pck" has the same size as the original (ogv) file.
And when I enable "debugging enabled", I can read an error :

The most strange thing is that, everything goes fine when I press "play the project", or F5, before the export process. I am working with OGV file.
