Even if I have a CD-Recorder, I have never used to capture LD audio tracks, as I don't see the point to use it for this... indeed, you have to record the CD and then rip it into your PC; even if it will take few minutes more than direct capture, it's still longer... multiply those few minutes for a large collection, and the total waste of time will be hours, if not days!

There are, of course, few exceptions:

you have NOT a digital input on your sound card
you want to capture the analog tracks and the CD-Recorder ADC is better than your sound card's one
you want to capture both analog and PCM tracks at the same time (to prolong the life of a precious laserdisc player and/or cut the capture time in half)

If you have some minutes, take a look at this post.
