Have you tried burning at a higher speed?  I had a drive that would burn 
perfectly at all speeds other that the minimum.  The law of universal 
perversity (known by other names!  8-)  )   ensured that it was when I 
_had_ to quickly get a CD out that worked perfectly that I tried the low 
speed burn, and produced several coasters before successfully going back 
to my top, or next to top speed.
