Is it an EXACT copy?

[Liace]

I am about to buy a DVD burner for my new computer (everyone seem sto recommend Pioneer A04), so I think I will get that. But before I start backing up my DVD's, I was wanting to know if it is an EXACT copy. What I mean is, do all of the extra features (such as behind the scenes stuff, and all of the other extras) burn on the copy as well? I tried searching for the answer but didn't come up with anything. Please let me know. Thank you very much for your help.
