Hmm, completely slipped my mind, I had an Athlon 3200 that was 32 bit, and 
forgot that in there somewhere they went to 64.  Anyway, try this:  Start out 
with a speed that's half of what your running now, and see if it trudges its 
way through.  And, yes, it could be that the CD/DVD burner doesn't like the 
faster processor. 

Here's something to check running in 32 bit mode, how many procs are active on 
your system?  On my AMD X2 box, I had to run 64 bit native mode to get both 
cores to run.  Some apps were running horribly, and if I remember right K3b 
was one of them.
