I too only do 1:1 copies. I've started a couple of threads about the 1:1 backup copies still having protections. I've even done backups of the backups to get rid of the protections and still no good. I assume that due to the nature of the 1:1 copy, some protections are going to remain in the ISO. When I use AnyDVD, I usually have AnyDVD running in the background and let UltraISO create the backup. I've also used CloneCD to do the images, but after comparing the images with a hex editor of both UltraISO and CloneCD with AnyDVD running in the background, I concluded that the images were always the same. Lately I've switched to letting DVDFab do the ISO clone. One DVD that both AnyDVD and DVDFab have problems with is "The King of Kong - A Fistful of Quarters". I've created ISO images with both programs and both of the backups play differently than the original DVD. While you eventually get to the main menu, and the movie seems to play fine, along with the other features, how you get there is like taking two different roads to get to the same place, and neither road is on the original map. Very weird.
I once suggested to a friend, who also uses AnyDVD and has had the same frustration as me lately, that they could create a module for each movie that comes out. Each module would include the modified IFO files for that particular movie and whatever else information needed to produce a complete fully working DVD. Of course that presents a whole boat load of other problems. Slysoft would have to hand craft the module for each movie(+region) and then any variable versions of it. Probably impossible. They could charge $10 for the program and then $1.00 per module. They would probably make more money, but have to hire a thousand people to do it. Who knows, just another thought I'll probably get flamed for.
Oh well, I feel for James and the team and the rest of us. The movie companies are only making life miserable for us all.
