How do I get my DVDROM drive to read (extract audio/data) faster?

Let's see, for hardware:

P3 600EB
896 MB RAM
4x Sony DVD-ROM capable of about 40x CD

The program I am using is actually an MP3 ripper called Exact Audio Copy. It used to copy WAVs onto my hard drive at like ~12x, but now it only goes like 4x. This is also causing a problem with my cd burner with direct driver-to-drive cd burning. I believe I need some kind of new aspi drivers.
