Using dvd decryptor I've backed up about half a dozen movies. Of them half worked great with menues working and movie playing fine (even one with a complicated menu), yet the other half don't work. None are really complicated like the matrix or anything, as a matter of fact one of the ones that DIDN'T work was a cheap $10 dvd with no real extras. They all do the same thing, they just spin and eventually my Sampo DVD player says 'no disk' and locks up. BTW on one that Didn't work (Ronin) it made 2 files a .iso and a .dvd, but when I burned the file with Nero I only used the ronin.iso and didn't do anything with the ronin.dvd file.
