As to DVD to iPod Ripper, as far as I know, Wondershare DVD to iPod Ripper is a good choice.
Also, there's a Mac Version --- Wondershare DVD to iPod Converter for Mac.
Google it, you can search it for sure!

I use imtoo's prodcut, although it is the shareware, but I think I will never regret spending money on this product.

Wondershare DVD to iPod Ripper never lets me down.
Along with the latest MPEG-4 video encode technology XviD & H.264, it helps me easily convert all kinds of DVD movies to iPod video MP4 and iPod audio MP3 and M4A, put DVD on your 30GB or 80GB iPod with 640 by 480 resolution.
Its Mac version is also a good choice for Mac OS users.
