I have a 15" Mac Book Pro 2.16Ghz, OSX10.4.10, 2 Gigs ram.
It has an internal "Matshita DVD-R UJ 857-D" superdrive.
Yesterday it just stopped reading some DVDs & CDs.
Not all. It does read some Memorex DVDs & CDs.
I've found no consistency to the problem yet.
Was wondering if anyone has experienced the same problem.

Many thanks.
