I have an eMac and recently bought a LaCie external DVD burner. I've worked through the maze of backing up DVDs to my hard drive, but have one DVD (Duran Duran: Live From London) that the superdirve just won't read. It plays fine in my set-top DVD players, but the computer drive won't read it. It sits in the drive, and the drive tries and tries to read it, but it seems pretty stubborn. All the software (Mactheripper, DVD2one, and Toast) says there is no disc in the drive, and there is no disc image on the desk top.
