After my experience with it, the v4 of 1clickcopy (before it went Pro) never mastered the titles correctly. Given they went back on their promise of life free upgrades (they used to have it at their site and I have the old eula + other records that so stated), I'd say
1click can't be trusted to keep its word. Given that and Slysoft has kept its word, I'd highly recommend
CloneDVD2 and
AnyDVD--I've never had a single problem with either--whereas I had trouble several times with 1click not 'properly mastering' the title.
By the way, I used that free decrypter with 1click and found it rarely worked; I had to buy AnyDVD to do all the decrypting anyway. Buy it, and you won't have to worry about trying to find 'free' decrypters--and it is always frequently upgraded (sometimes within hours) after new copy protections are discovered.
