When no disc is in the drive, the directory listing clearly shows that I have a DVD-RW drive. However, as soon as I put in a DVD-R disc (I tried with various blends), the directory listing shows that I have a CD Drive. This means that I am not able to write to the disc since the CD drive does not recognize my DVD-R disc. When I look at the property of the drive, it shows zero free space. I went to Sony website the download the latest 1.51 driver, but during the installation, the screen told me that I have already have the driver. I am trying to burn a movie that I have created from mpeg to Video files using Nero and DVD Shrink. the video is ready to be burned except I can't get my DVD+/-RW drive to work properly. I read up on various forums and can't seem to find a solution. Can someone help? Thank you!
