However DVDs and CDs may differ in thickness or weight, it is probably  
not the cause for your recent experience.  During three years of  
continual usage, with frequent reading/writing of DVDs and CDs in its  
SuperDrive, my iMac G5 (20", iSight) has never "shot out" any CDs from  
its side slot in the way that you described.
