Sony DW-Q30A Under Windows XP

I have an application that when I close it under windows 2000 it will make a backup of the database. I installed Windows XP added a Sony DVD Recorder but am using CD-RW discs which it can use. When I close the application it tells me there is problem duplicating the database make sure the path is correct. When I try to copy files directly to the drive, I get a windows message that says that files are waiting to be written to the disc. I just want to copy files normally as if the DVD were a hard drive. What is going on under XP? I want my old way of doing things back.
