I was successful over 200 times copying Bluray to bluray. All of a sudden I get ejected with 50% to 99% done and with the message "failed to burn. Do you want to burn another". I say I do, and I keep getting the same results. I have reenstalled dvdfab several times and get the same results. I'm using Optical Quantum blanks with over 200 past successes. Any ideas. Thanks
