Archiving DVD's with Linux?

Ramses0 asks: "Now that I've got my Linux box 100% functional with full DVD support, I want to archive all my media to it's 60gb hard drive. Since I don't have 60gb's of OGGable CD's, I started looking with a lustful eye at ripping and encoding my DVD collection to the hard drive as well. Most of the guides out today are targetted towards windows software, which is not an option for me. The only reference I could find to encoding under Linux is about ffmpeg on the DivX website. What is the best file format to target? DivX? VCD? What tools are available under Linux to encode DVDs? Why isn't there the equivalent of abcde for DVDs?"
