Occasionally, I will try to rip a CD and many of the tracks will have to re-rip 20 or 30 frames. But I have noticed that sometimes if I cancel the rip, eject the CD, and start the process over, it rips quickly and does NOT need to re-rip any tracks, and all tracks get an Accurate Rip. Why would this occur? (I believe that my CD ROM is fine.) Can I assume that since I am getting Accurate Rips, all is ok? Thanks.
