The lates updates for dvd43 and dvd shrink are even copying those nasty Sony/Columbia Arrcos protected dvds; I never had any problems with Disney movies at all (not even with the older versions...) Anyway, try updating your dvd43 and dvdshrink. Burn the movie to your hard drive, then use Nero (or whatever other program you prefer) to burn it to disk. If that doesn't work, then the movie is probably scratched or defective. Good luck.
