make a single good copy. Since I have my new computer with ATAPI DD DVD Drive, and using Ritek (Ricohjpn) DVD media I cannot make a single good copy. (Using: DVD Decprypter, DVD Shrink & Nero Startsmart.) Before with my less sophisticated equipment I was able to rip & and copy. I was even able to copy onto Memorex with no trouble. I do not know where to look for the problem. I would appreciate any hints. Thanks for your interest in my difficulty.
