Okay, if you want to rip any movie what so ever, use Ripit4me, as it can handle anything you through at it, including the new PuppetLock, Arccoss, etc. It uses DVD Decrypter, the best ripper around, yet it is no longer continued, thus the need for Rip it for me.
However, if you just want to rip the main movie, you can use DVD Decrypter in IFO mode, with file splitting set to "none", or use Ripit4me in "Movie Only" mode.
Then there are several programs that will convert the video to ipod mp4 avc/aac. A good free one is Videora Ipod Converter, another, more powerful and sophisiticated one is MeGUI, which is what I use, but you have to know what you are doing.
That I think about it, there is another prog called Xvid4PSP, powerful and relatively compact. It's free as well.

Just my .02 cents.
