My dad just got himself a CD writer for his computer.  When he uses
Adaptec CD copier, it makes a CDDA file from the CD audio (digital), and
writes it to a CD (digital).  Somehow in this process he's getting pops in
the audio.  This makes no sense since it's all digital.  Every CD I've
tried burning in this thing does it.  It appears to be doing it on several
brands of CDRs so I don't think it's the media.  Anyone ever heard of this
before?
