Audio Systems: CD-R Discs Not Playing, 2008 toyota camry, toyota camry

Question
I recently purchased a new 2008 Toyota Camry which came equipped with a CD Player.  I had a bunch of legally downloaded and burned CD-R discs that were, for the most part, played once or twice on my home system and were not scratched nor did they ever have labels on them.  The CD Player accepted the disc and began reading them and, indeed, playing about a dozen or so songs on the disc when after about 20 to 40 minutes the playing would halt.  I then was unable to eject the disc.  After shutting the power I would wait a minimum of 10 minutes or so and then was able to eject the disc.  If I put the disc in again it would play and then stop after a period of time.  I had the player replaced by Toyota but to no avail.  Toyota claims they don't understand what is wrong.  Do you have any suggestions.  I have used discs from various manufacturers and neither brand plays.

Answer
Toyota radios are not made to play CD-R discs  but i just play a mp3 and regular cd on a new solara and it work fine the cdr took longer to play but it work   in this case it is better to put all your music on mp3 or use a ipod
