I use this with either Sony or T-Yuden DVD-R disks to record movies on tv. My problem is sometimes after I finalize them, they come back as DVD-Ram disks. So if I want to copy them to my hard drive I can't. My Lite-On burner doesn't recognize DVD-Ram's. These disks show up as audio cds. However, using DVD Identifier they read as DVD-R disks. Can someone explain this?
