I got what I considered to be a great deal when I picked up a spindle of 50 Sony DVD-r for 20 bucks at Staples. When I checked the package it said made in Japan so I was confident that I was getting good quality. When I got home and ran one through the DVD Identifier program they came up with a code of D11 but the manufacturer was still listed as Sony. I had never seen that b4 and now I'm afraid to try them out. My mistake was when I looked at the package marked made in Japan it was for the "dash R's and I had bought the "plus R's" that are made it Japan. Should I give these a try or take the spindle back to Staples. I always use +r's and really thought I was getting a great deal!!!!!
