I have Nimo Codec Pack with all the decoders and I also have Divx 5.0.5, which is the latest version. Still, when I try to view some divx dvd rips, I get this green fuzziness that happens to people who don't have the codecs. The thing I can't figure out is that I have all the codecs. Should I upgrade to Windows Media Player 9.0 or something???
