Not true. My Cd changer in my Trooper will sometimes play CD-Rs and
sometimes not. I have found that recording them at 4x or less works much
more consistently (although still not always 100%) I first noticed the
difference when I upgraded to a faster CD burner that would record at up to
48x and found that the Trooper's CD changer would lose tracking quite
easily, so I tried burning at the slower speed and got much better results.
The explanation for why this is so is that the CD burner records by
darkening (with the laser) spots on the blank disk to mimic the "pits" and
"lands" that represent the data on a pressed CD (the laser either reflects
or does not reflect off each pit or land thus representing a 1 or a 0). The
slower recording speed gives the laser more time to thoroughly darken the
"pits" creating a greater contrast between the 1s and 0s. Also as the CD
player gets older the reading laser gets weaker and the optics get dirty
thus making the player more sensitive to the reduced contrast.
