Anyone use DVD to MPEG ripping software?

I found this Mac port of the old BeOS app called Handbrake.

It's only beta but it rocks. Very easy to pull individual music videos off of DVDs for example. Great for carrying around mpegs instead of whole DVDs for favorite stuff you might not want the whole DVD for. Also for renting concert or video DVDs or checking them out from a good library and ripping your fav videos. Anyone else do this? Other apps? PC ones?
