I haven't seen the deAgostini copy version of McLintock. Generally their prints tend to be good but I would suspect it is not a remastered version as Batjac made such an effort to enhance their negatives and remove blemishes, color fade and scratches etc.
Play.com are selling enhanced edition for £3.99 at present and it does have a lot of extras.
Thanks Mike. They are better than Amazon, who charge postage. Worth it just for the extras.
