Videora can convert video to ipod but can't convert dvd for you, I always use aimersoft ipod converter suite, it can easily convert dvd video to ipod with quite fast conversion speed and excellent output quality, that's really good, you can free download it from its official site:

After you finished the conversion, just open iTunes and click "File" to add your videos to iTunes library.
plug in your iPod to computer, then iTunes will detect your iPod as a device.
Select your iPod device on the left panel of iTunes, click "Movies" tab, check the videos you want to sync and click "Apply", done.
