The Fog was one of the recent releases that gave certain users of fab, problems when backing up “complete disc”. I’m willing to bet these issues will not be reproduced when copying “main movie” only. The issues relate to recent copy protection giving rise to disc structure problems; freezing, continuous looping of sectors, poor or failed navigation of the disc menu and to a lesser extent, the player remote. This is only seen with fab and complete disc mode and not consistently among all users.
If you’re able to use AnyDVD, as deanimator did, and burn with nero, dvd decrypter, Img, etc., you shouldn’t have a problem with complete disc. Not sure about bitonio6, whether he did main movie or was simply unaffected by fab’s issues.
