  A "buffer" is an area of memory being used to collect data from one 
process and suplly it to another.  A "buffer overflow" occurs when the 
source tries to put more data into the buffer than will fit -- usually, this 
means that the extra data wiles sout some adjacent memory structure that was 
supposed to mean something else, and trouble ensues.
  A "buffer underrun" occurs when the receiving process wants more data than 
is yet available.  In most cases, the receiver silently and correct deals 
with this by simply waiting until the data it needs is available.

  There is ONE common case where that won't work, and that's where the 
receiving process is tied to some physical hardware whoe timing cannot 
talerate such a pause.  And the most common of these is -- burning a CD or 
DVD!

  So if you just started getting these, there are two basic possibilities:

1. Your burning drive and media are capable of a burn speed that your CPU is 
having trouble keeping up with.  Try burning at a lower speed, or upgrading 
to a faster CPU....

  OR

2. Something is using up too much of your CPU resources, leaving not enough 
to burn your disk in a timely manner.  Some people never notice 
spyware/viruses/malware until its cumulative effect impacts the performance 
of legitimate applications....
