The Ots Labs CD-DA subsystem has a caching system that will store a processed CD's information, such as track information and mix points. The cache system will call on the stored CD information, when the CD is played at a later date, therefore eliminating the need to process a played CD again.
If at any stage you require the CD cache entry for a CD to be cleared simply go to Main Menu -> Options -> Remove Cache Entry for CD in -> and select the appropriate drive.
