I've found in the past that problems with CDs are two-fold:
1) Deterioration of the media itself (which was particularly bad in the
early days)
2) Incompatibilities with media and/or the burning process across drives
and platforms.
The latter cropped up time and again, enough that I decided it was too
risky to keep data on CD because I might want to come back to it 5 or 10
(or more) years later and find that no hardware that I had available was
capable of reading it.
I don't know if DVD is any better; I developed a deep mistrust of any
optical media and so I avoid it except for transient stuff where there's no
alternative.
