I will see about buying a CD player cleaning disk. I suppose they
still make those.

I've used 3 different spindle of CDs before I started the thread. I'm
happy to try 'better' media if I can determine what that means without
guessing.

Here's an example. The first printout is the original CD-R I copied.
It plays fine in the car. The second and 3rd printouts are copies of
that CD-R. Neither plays in the car. However other CD-Rs copied the
same way do play.

<ORIGINAL CD-R>

Both of the 'bad' CD-Rs are rippable in iTunes on my Windows laptop.

The issue here is clearly the car, but only with some CDs, and those
CDs are consistently bad.


I will see if I can decipher the cdrecord help file to try burning a
copy that way.

Thanks,
Mark
