You will be surprised to know that DVD ripping is not half as difficult as you thought it to be. Though the task requires a little knowledge but can be carried out perfectly if you try your best. DVD ripper is a device that is used to convert the audio or video data, present in the DVD format to the one in digital format, which can be copied to the hard disk of a computer.
A video DVD ripper is capable of compressing a video file into DivX, avi or mpeg-4 whereas an audio DVD ripper has the capability of compressing an audio file into mp3, ogg or wav. To completely rip a DVD to your hard disk, you either need both audio as well as video DVD rippers and a video DVD ripper, which can perform both the functions.
These DVD rippers are being used extensively as not only are they capable of ripping a DVD completely to a PC hard disk but can also put the same into a Video ipod.
