I've had a reader drive badly scratch a DVD.
The user even put the DVD in an ancient CDROM drive and tried to read it - of course the problem had nothing to do with using a CDROM, the drive had severe mechanical problems.
A mass-produced CD/DVD can't be written to even by a writer drive, the power is far to low.
I had a 2 CD set that was stored in a CD cabinet with its brothers go milky white and unusable. So it could be a bad DVD.
Is it posible for the electronics of your reading laser to go birko and damage the surface?
Be careful that your skin doesnt start to go green every time you get emotional...
