It has never been necessary for me to run any other proggy including FixVTS thought AnyDVD and CloneDVD2, if they run up against a movie it cannot handle they come out with an update within hours, maybe a day or so. No movie is that important that you cant wait a day to rip it. You can always watch your original till their update is compeleted. This is true for all decrypting software including FixVTS that has not been updated for some movies. FIXVTS is not a decrypter anyway, it only makes your files DVD compliant.
