Dvd burner problem

I am a newbie at this. Maybe someone can hep me out. I tried making a backup of The Departed using dvdshrink and it asked me to select a dvd region. Problem is that it won’t let me select a dvd region in the properties of the dvd burner. It now will not read eithe dvd’s or cds in the drive. I have a Sony DRX -830U. I need help. Please.

I just did this one this morning (R1). Reboot and use DVD Decrypter.
