I just purchased a Sony DRU830A DVD burner and set it as master. My old DVD burner drive is a HP DVD300i, which is set as the slave. I keep getting I/O errors when trying to burn DVDs using DVD Decrypter on the new Sony drive. It seems like there is some kind of compability issue. Has anyone else experienced or know what might be the problem? When I remove the HP and just have the Sony installed as the master, it seems to work fine....burns DVDs with no problem. Running on Windows 2000 O/S. Any help would be appreciated. Thank you, Joe
