There is a possibility to copy your DVD to your iPod. You can copy any DVD from your collection to your iPod for viewing it on the go. All you need is some spare time, right tools and software.
Mac users are a bit luckier, since they already have a solution - open source Instant HandBrake. It rips DVDs and converts them to MPEG-4 format (which is iPod-friendly) as well. Windows users need 2 programs: DVD Decrypter and Videora iPod Converter. You will have to use DVD Decrypter in order to rip the contents of your DVD to the hard drive. Then you will need Videora to convert the contents to MPEG-4. After that, you'll make use of iTunes to copy the movie to your iPod. Check out a step-by-step tutorial below.
