I have some CDs I made with my old band that don't play in the CD players in our house or our DVD player. I know that the rewritable ones aren't supposed to play in standard players, but these are the proper kind and they used to play in my old CD player that broke a year back. They do, however, play in my computer's CD player. Also, I have a CD by Front Page with Dominique DiPiazza that has the same issue where it will only play in my computer's CD drive. Anyone know why this is?
