Copied DVD plays distorted

I went back to my home town this weekend and borrowed Pasolini’s The Gospel According to St Matthew from the Hornsey Library and copied it, but I don’t remember if I used MacTheRipper to decrypt it or I just copied the DVD content to my desktop, anyway now that I burned it on DVD it plays distorted on my DVD player, shows green squares etc. and says “Unable to verify encryption” or something like that - on my mac. Is there anything I can do to save it?

If you do not own the DVD you do not have a right to copy it. This is considered an illegal post and will not be discussed here. Thread closed.:cop: Buy the DVD then back it up.
