Yesterday, I made my first back-up of a DVD-A disk with DVDClone(demo). This is a recently made HTPC with NEC 3540A dvd burner and it's been fine since I made it in early December. It also has the NVIDIA decoder installed as well. Now when I install a DVD (homemade or commercial) the DVD attempts to read it and then the whole system locks up with both WMP10 or MCE. Any ideas or is the burner caput? Thanks in advance.
