hello APSM
 
first, its really weird that your drive reads only DVD's.. have you tried playing an audio or VCD? 
Try using Nero's Drive Info Tool 
ftp://ftp6.nero.com/tools/InfoTool.zip  
 
it detects your optical drive and double checks the features that it supports.
if CD's really wont play, and the laptop is still under warranty, i suggest you bring it to the authorized service center for repair of the optical drive. 
======== 
if replacing the optical drive is not an available option at the moment, i suggest you try "
WinToFlash"
