Thanks for the hint. I've now read this article, too. Even with this
knowledge, gcc 3.0 produces faster code than icc. The reason might be
that I use only a Pentium III and the big improvement holds only for
Pentium 4. Another reason might be the rather special scene that contains 
mainly a slow media container. 

So far, I have tested some combinations of options that make sense. I will
try different scenes and maybe a different processor later.

Thanks again
Thomas
