I just bought 2 new releases, 'Full of It' and 'Blade House of Chthon'.  I back up all my DVD's now, since I'm tired of buying repeat new DVD's because the originals get abused by family members & friends.  I normally don't have a problem with any of them, but I have run into these 2, which don't work on DVD Shrink, DVD Fab, DVD Decrypter, RipIt4Me or the latest version of DVD Cloner, which gives me an error message of 'failed to open movie'.  Neither of these are really mainstream movies or blockbusters, so I am puzzled why they are problem discs.  No scratches or defects appear on either disc, purchased brand new.

If anyone can help me figure this out, it would be greatly appreciated!
