pony up and buy it....I think the value & security of being able to back-up my DVD's far outweighs any cost of this software. While I won't say it is the best (there is always something new coming out) I will say I have found no need to own anything else.
Until that changes this is where I will stay and recommend to anyone else I discuss DVD back-up with the same.
So far (and I've tried many paid & free programs) Slysoft is by far the best value in terms of quality. There is no reason not to have the complete software package by SlySoft. Even without the value coupons (gives on average $20 off) the entire package has more value than not. Just buy it and be happy!
