I have so far had to purchase mask 4 times My kids love the movie but they don`t take care of the dvd. I have tried for 2 weeks to copy it so I can give them the copy not my new tape. I use dvd shrink and dvdregion +css to backup all my dvds. When I try to back up mask I get a error :invalid dvd navigation structure. Is there anyway I can get around this to copy it. Even though the movie now costs just 5.50 At walmart. To keep buying it is getting to be an expensive movie.
instead of region free try using dvddecrypter or dvd fab decrypter(both free) to put it on the hdd. It sounds as if your just dealing with copy protection that shrink or decss can't deal with. good luck
if I were you I'd do what L8ter mentioned...... rip to the hard drive and keep it there! Use Shrink and whallllllllaahhhhhhhh! you'll always have a copy on the hard drive and just burn it! Good idea!
