Dvd shrink seems to duplicate

hi all
my problem is with dvd shrink i am trying to back up the red hot chilli peppers dvd but dvdshrink seems to duplicate each title so it wont compress down enough. any replies gratefully received

Not sure if this helps or applies, but I’ve noticed a similar behavior with some dvd’s in “copy entire dvd” and nero recode … sometimes the only thing to do is use the “remake a dvd” feature, which drop-kicks the menus and just puts the content you want on the disk. Some dvd’s have really complicated menu structures, where they index the same .vobs again and again as different titlesets. I don’t know if this is to foil unauthorized copying or just creative menu authoring; but it does put a rinkle in the former.
