I've been using imation dvd-r for DVD shrink + DVD decrpyter purposes, but recently I ran out and I got some Verbatim DVD-r from Hong kong. Now everytime I use the Verbatims to burn, it gives a power calibration error right at the start of the burning process, when it is writing the lead in. I went back to some older dvd-r such as imation and Mendi and they all worked fine. But everytime i want to burn the Verbatims with dvd decryptor , it just gives the same error. Even when i used nero to burn it still had power calibration error. I have my lastest firmware so im guessing its just the DVDs which are either fake(from hong kong) or faulty.
