This topic seems popular, I thought I would add my observations.
My laptop plays dvd's that have content (data or video). It reads blank CD's.
I have had problems with reading both Sony and Memorex 4.7GB BLANK DVD's.
I could not burn anything to a DVD.
Before replacing my DVD drive I purchased 50 Verbatim 4.7GB DVD's from Radio Shack. ($12.99 for 50)
After trying several each and every one has been read and used perfectly.
I have noticed that my older Sony DVD's have a red tint on their surface. The new Sony's have a blue tint.
It seems there may have been a recent change in the manufacturing process.
