there are two ways that personal computers can play a CD. The first method 
(which KsCD refers to as direct digital playback), is performed by reading the 
digital data from the CD using Digital Audio Extraction (DAE). This data is 
sent to your machines CPU which converts the digital data to sound. This 
method requires a CD drive that is capable of DAE (most new drives are) and it 
requires some CPU processing time to generate the sounds you hear.

The second method uses the internal circuitry available on most CD drives to 
read the data and generate the sounds you will hear without using your 
computers CPU. This data is transmitted by a dedicated cable directly to the 
sound card in your computer. This method requires less CPU proccessing time, 
but it does require that the dedicated cable be connected inside your 
computer. Not all computers have this connection.

The checkbox labeled Use direct digital playback determines which method KsCD 
uses to read the audio tracts. If there is a mark in the checkbox, the first 
method is used. If there is no mark in the checkbox, the second method is 
utilized.
