My method for DL backups: 1) Rip with AnyDVD/DVD Decrypter (file mode) 2) Remove all warning nonsense with VobBlanker 3) Create an ISO with IFOEdit or ImgTool 4) Burn with ImgBurn (including verify, just for the hell of it) Takes a touch longer but I despise warning messages, etc. (especially those which prevent your remote's menu button from working)
