I often burn copies of my oringinals so I can bring them with me and not worry about them getting scratched up or lost or something....
and for that I use DVDFab Gold, I bought a legit copy of it...its like $30 or something but IT IS WELL WORTH if you ask me...I can copy just the movie or the enire DVD, I can do split DVD5s or a single and it just degrades quilty a bit...I like it
Get a small program from Slysoft called AnyDVD. It decrypts copyrighted dvds on the fly so that any program can burn them. I use that in accordance with 1click dvd copy pro. Have yet to run into a problem.
Apollo DVD copy. You can choose if you want the main movie or the whole thing, split the disc into two, choose which audio languages you want, which subtitle languages and the works. Very very easy user interface, just a click of a button too! I highly recommend it.
