25 I don't think there's a way to do bit-for-bit compare of audio CDs...
26 if it's a burning issue I would try burning at a slower speed (as slow
27 as you can tolerate waiting for).
29 Maybe your car's CD player/laser is dying. Perhaps try taking some old
30 CDs that you know used to work and see if they still play okay. The CD
31 player in my car for the past month or so has decided to be unable to
32 play a CD without skipping like crazy. It is maddening.
