a little update on my problem. i found this page
http://trendprofi.bei.t-online.de/xvidhelp.htm and the 'misty' one is my prob, so i uninstalled the whole nimo pack and reinstalled it without the ffdshow. but now the movie played, but the video is shaky, like earthquake :(
any idea how to solve this prob? could it just be a prob with the movie itself?
