Backing Up DVD's

I have around 70 DVD’s, and I want to just watch them from my computer. I first thought about just ripping to avi/divx, which is good, but you lose metadata. Also, with Media Center Edition 2005, there is the My DVDs area which you dont get to use with avi’s. I decided to use DVDShrik and DVDProfiler to just rip my dvd’s to my hard disk in the raw format. I figured if I wanted to then convert to avi I can. One thing is though, I need more hard drive space. 🙂
