2 more cents.

I've tried several brands of CD-Rs always using cdrecord.  IIRC cdrecord
-v will rate the CD-R with a letter "grade".  The better the grade the
more likely the burn will succeed.  Currently, I have a stack of blank
Verbatim CD-Rs which rate an A (or A+) by cdrecord.  I have not
generated a single coaster at 40x.  Some C rated CD-Rs have consistently
failed at speeds as low as 8x (there was no speed rating on the
package).  

The moral of the story: get better CD-Rs.
