Cover Flow scroll speed

Is it possible to increase/reduce the speed in which the Cover Flow mode scrolls through items (when using a scroll wheel on a mouse)?

I have a lot of movies, and I like using Cover Flow to preview all of their covers. However, I would prefer it if when scrolling with the wheel on my mouse it wouldn't skip to every 4th/5th movie on the list, and would instead scroll through them one-by-one.

Any ideas?

Thanks
