I think in addition to how fast your computer is, also the kind or version of codec your using makes a difference also. I have used autogk quite a bit and it is slow but I use a codec I found free on Internet. If you want some thing really fast, at least on my machine try clonedvd mobile from slysoft.com. 21day free trial. I did a movie disk today in less than 30 minutes. That depends on a lot of things as far as speed goes.
