I fed DVD Decrypter a DVD with some DVR archives on it (local cable op's DVR, not Tivo) but DVD Decrypter wouldn't recognize the disc as a DVD. The disc was recorded in VR mode and is not finalized yet. The disc contains a folder named DVD_RTAV which contains an IFO file named VR_MANGR and a VRO file named VR_MOVIE. Is DVD Decrypter supposed to be able to recognize this file system?
