Show buffer underrun protection counter at the end of the burn process –
When checked, a counter will appear at the end of the burn process to show
progress. This way you can actually see how many times the recorder paused and
prevented a buffer underrun! It will also explain why it took longer to actually burn
the CD than it should.
