I found another DVD Ripper software, [Only Registered Users Can See Links. Click Here To Register] is not a bad choice if you're looking for an easy to use program that includes some nice features and will allow you to rip to most any format. I think for the price it's worth it if you'll utilize all of the features and will be doing more than just converting or ripping to the new iPod ect.
If you just need to rip movies for the iPod, then I'd go with one of the free versions I already looked at.
Pros:
+Fairly easy to use
+Also give you the ability to crop, watermark or add effects
+Relatively fast
+No ability to change aspect ratio
Cons:
-Expensive
-Automatically selects everything on the DVD
-Large final file size
