I've successfully ripped Das Boot, the director's cut...double sided dvd....over 9 gigs of movie..no extras. i ripped both sides with dvd decryptor, processed each with dvd2one. then used vob edit and ifo edit to connect them into one dvd movie. then processed again with dvd2one to shrink to one 4.7 dvd. it looks fantastic on a 31 inch tv.....quality is excellent...can't see any difference from the original. dvd2one is absolutely the most incredible sofware available today - Bar None!
