When X tries to start the tv flickers for a while and then there's an error log displaye saying that no screens were found. I connect trough a composite cable. WHat might be wrong??

It all looks good to me the only thing that I can think of off the top of my head is that I think I heard that the Vert refresh is different for PAL.

It worked very good after i changed to PAL-B.
