Welcome to fixya support,

Hello,

incompatibility is the cause of the problem. There is nothing wrong with both your player and the computer made CD's, they are not just clicking with each other.

The Pioneer PD-M403 player is also an old model, this could cause the problem.

There is not settings whatsoever that you can use ti solve this problem.

Take care.

CDs go in the Upside Down position. Your PD M501 will accept PRW 1139, PRW 1141 and 163.

Sometimes the little ball bearings that keep the cart trays separated come out causing tray jams.
Make sure your tray retracts all the way into the player flush with the face plate, gently push it in while retracting for those occasional no-read situations. (Also for Denon that takes these same carts). Also note that the CDs go in the Upside Down position.
