Waves from DVDs, as far as I know, you have to use an audio program and record that specific thing sound byte on the fly. So, for example, Cool Edit or hell even Windows' sound recorder, (if you want crappy quality, anyway).

As for mp3 ripper, a lot of programs do that, and hell, good ol' Winamp does it, now.

Anyway, try download.com for your audio recorder. Most of that stuff is shareware and (mostly) trial stuff. Some programs give you complete freedom for 30 days. So if you need something just for now, that's your best bet. If you need an lifetime solution, yeah, someone else will have to give this a looky.
