I already solved the problem. It was not the file but my codec was corrupted. I just had to install again divx 5.1 and everything worked fine. So if you see scribbles and your divx all messed it must surely be that your codec has gone bad.

PS: If you install 5.1, you must first remove the old ones with its uninstall feature. Don't let 5.1 remove the old ones, that is what caused the corruption. I sure paid for being to lazy.
