What type/speed processor do you have?

As others have pointed out, CD burning with IDE devices does require a
lot of CPU time, and you must allow it to use this time or you'll get
coasters.  The only way to permanently solve this is to use SCSI hard
drives and CD burners.  But a faster CPU will lessen the impact.

You can also try lowering the speed at which you're recording the CDs.
