Not disputing any of that, but remember that I use a standard methodology for 
mastering and burning, and the results have always been fine.  Whether I burn 
on the computer from my own masterings or on the stand-alone player/burner 
from input, I always check the result on the 'other'.  Until recently they 
were fine.

I'm convinced that a recent upgrade to something - maybe a libs package - has 
upset the applecart.
