What is the best way to back up an entire library of dvds?

"I personally used Fair Use Wizard on my DVDs so I can play them straight from the network without hunting for discs.

I ripped them all to 2100MB avi files in XViD including the full AC3 surround track and at the full DVD resolution, and any quality degradation is imperceptible to me. If you are more sensitive you may need to set it a bit higher, or you can ask FU Wizard to rip it to an avi that contains the original data stream from the disc, which should be a very quick rip, but might take about 4-6GB per movie instead."
