In this procedure, I am reading with and writing with, the Pioneer Burner. The problem does not happen when I read from one Burner and write to the other. Only, when switching from the original disc to the blank disc. AnyDVD is in use during the following: 1. I backup a DVD, and after the reading cycle is over and the writing cycle starts, I get the "Oh! No Error"- stating a media problem. 2. I now use DVD Shrink to rip the DVD to HD and burn back to the Pioneer DVR- 115D Burner. No problems-the copy is perfect. Firmware of Pioneer is 1.18 and Version of CloneDVD2 is 220.127.116.11 If I use CloneDVD2 and burn to my Plextor 760A Ver 1.07- no problems occur. Is it the Burner or the software?
