I'm experiencing problem with my DVD burner. I can't burn DVDs. I can burn CDs and watch DVDs though. I tried using different DVD-Rs but it didn't work out. I also noticed that whenever I insert a DVD-R my optical drive is displayed as "CD Drive". My burner is Lite-on DH-20A3L07C and the application I use for burning is Nero Express Essentials 7.
When I insert a DVD-R it is recognized as "Blank CD":
This is a known problem in Windows. Simple solution: ignore it.
If your Transformers DVD is an original disc, you just can't copy it to a single layer disc. Since you are using Nero, suggest to check the Nero subforum on how to make a backup.
I just included that as a part of my observation. The real problem is that my drive can still read CDs & DVDs and also burn CDs but it can't burn DVDs anymore. It used to work before...
