[Impress] Movie stops after animation in the same slide

Hi everyone,

I have a slide with several animations. The first one is a movie, that starts and repeats itself. So far so good, the problem is that after I click to add a new animations on the side of the movie (so not an animations directed to/from the movie), the movie is been replaced with a question mark as big as the movie.
Solutions?

Thanks a lot
