So I have a pb and mini with similar stats. The mini is 1.5 ghz g4/512/combo and my 12" pb is 1.5 ghz/1.25gb/superdrive. Whe I rip dvds with my mini, it normally goes at 18-20 fps. I just got the pb and figured it would be at least the same, if not faster because of the ram(although I didn't think that would make a difference). But it's going at about 10-11 fps. What could the problem be? I use handbrake for both and I turned off all other apps. The pb is even completely clean; I haven't transferred any of my files over yet. I don't get it.
