I have a Sony DW-D22A / Liteon 1633s drive. I can burn regular dvd's just fine. But when I try to burn a movie to dual layer media it begins to write then it always has an error just after starting. I have tried several dual layer blank media and it always gives me unable to write errors. I am using the latest updated versions of clonedvd2 and clone cd. Can anyone help me with this problem that I am having?
