Hello, I have a harold and kumar dvd that I'm trying to burn by using DVD decrypter and dvd shrink. After the Decrytpter made the ISO file, I put in the blank DVD to burn it with Shrink. An error message shows up. I have never had problems with other DVDs. It shows this: DeviceIoControl (FSCTL_LOCK_VOLUME) Failed! Device :[2:0:0] Philips DVD842 6H01 (E(ATA) Unable to lock volume for exclusive access. Reason: Unknown (37) Abort, Retry, or Ignore.
