Hi Cornholio7,
Thanks for replying. What do you mean with ptp? If you mean P2P, like in filesharing network, the answer is no.
It is an original disk I bought directly from Pioneer, and want to backup before it gets damaged and Pioneer charges me the full price (270 EUR = 300 US$). Like said, I created an ISO and MDS of this disk with dvddecrypter, and want to burn that one with imgburn.
Like said, in my country, Belgium, laws explicitly state it is completely legal to duplicate a disk you originally bought yourself for your own private use; so I'm not violating any laws.
If you mean something else with ptp, I have no clue
