First I want to again thank everyone in these forums, I was basically a zero knowledge newbie and your guides and threads led me to shrink and decrypter and I,ve been backing up my DVD's with a 100% success rate. But now I have an error message that pops up everytime I go to burn with DVD Decrypter. It is: Device Control (FSCTL_Lock_Volume) Failed! Device [1:00] HP DVD Writer 300N 3.11 (E(ATA) Unable To Lock Volume For Exclusive Access. Reason: Access is Denied. Abort Retry Ignore I choose ignore and it burns the disc without apparent problems as it plays on both computer and player. This error appeared after several unevental copies but I now get it every time...any ideas on what I'm dealing with? I haven't made any changes to settings that I'm aware of.
