I have an IBM ThinkPad T23 with NEC 6500A DVD burner. The NEC spec sheet say's that it can use DVD-R, DVD+R, DVD-RW, DVD+RW, etc;. When using AnyDVD with CloneDVD2, it won't let me burn DVD-R's or DVD+R's. I can only use DVD+RW disks. When attempting to burn to a -R, or +R DVD using CloneDVD2, it say's: "No Recordable Media".
