Most computer users typically store their favorite movies onto DVDs since their storage capacity is considerably improved compared to CDs.
In order to make sure the train/car/boat journey does not seem longer than it actually is, one can always enjoy their preferred movies onto their iPod devices after having ripped the DVDs.
DVD to iPod converters will allow users to rip the contents of the discs to the format they choose, but it should be mentioned that MP4 videos are supported by the entire range of iPod editions.
Whenever the default settings are unsatisfactory, one will be able to adjust the aspect ratio, audio channel or sample rate of the source video.
