How can I avoid constant C drive reading for multiple cd duplication

[pavs]

I am very impressed with the free program as it maximizes the burn to the media and selects max speed. However I noticed it is always reading from the hard drive for every song for each burn. Seems unnecessary especially for over 100 copies. Before I purchase is there anyway to set it to create a ram source? BTW I was having over 50% copy rejects using other burn programs ...you can see the difference just looking at the cd as the start and stop edges are very pronounced with Express. The playback is super reliable from even the cheepo boom boxes. The free demo saved my a.. in a time crunch job. Thanks NCH!!
