I have a pioneer 106 burner. I have been making back up DVD's using Nero version 18.104.22.168. I have been using Princo DVD-R media, with no problems. Until recently! Now, every DVD backup I make sticks at the last couple of chapters of every disc. Please could someone help me with my problem. I have updated my Firmware for my writer to version 1.07, but to no avail.
