I have been using this app recently, and it works remarkably well. It used to be such a pain in the ass to make a rip of a dvd to divx or whatever. Rip, split the audio, encode, join, blah, it would take all night for one dvd. this app does it all for you and lets you choose the output size/format, you can even do Ogg audio (I dont really care about that, but options are always nice).
lets get backup copies of those dvd going fellas.
There are a few others that I havent tried, fairuse works well enough for me.
