Thanks,Submariner. Platinum.v3

I use DVD.X.Copy.Platinum.v3.21. I download it from
chinese website three month ago.
What's D or Z? I don't know. Would you please tell me?

Have you ever used DVD X Copy?
I just used it last week, it works good. But the only problem is that It adds a warning saying this is the
backup copy for private use. Is there are any ways to
delete this warning?

I used DVD X Copy platimium and copy the DVD movie directly from one DVD drive to DVD-RW drive on the same computer.
I used simple mode instead of advance mode because I can not figure it out how to use the advance. Because
I can not find any user guide or manual of this software.

Thank you so very much for your kind help in advance.
