Hey members, Looking for some advice. having a problem backing up my personal copy of gridiron gang. i use anydvd with my dvd shrink and when i open the disc i get an error message. "invalid dvd navigation structure". Does anyone know what this means? i have also been reading that the new anydvd update is giving people problems. i dont have the updated version. Do you suggest that i update my anydvd or wait until a newer version comes out with less bugs? Thank you all in advance.
