I have gotten and tried DVD Ripper Ultimate and Video Converter Suite on my Win7 x64 machine and I am getting an exception error and the GUI is messing up. I will try in XP Mode but like the movie I am trying it with "Manos the Hands of Fate MST3K discs 1&2; the worst ever made.
I vote for Air Video (app from the App Store). You set up a server application on your desktop and you stream (in Local Area Network and over the Internet) your videos directly. Moreover the app allows live video conversion!
Handbrake is the best for most DVD's. It doesn't get updated all that often so some of the newer encryption types it can't break. I usually use AnyDVD(HD version for BD) and than convert to whatever format I need.
