Convert DVD file for a Memorex Touch

[Fugitiva]

Hi! Recently I buy a Memorex MP3 Touch, it includes a MediaCoder to do the transcoding of the files, BUT I dont know how to use it. I tried several times, but I dont know step by step how to convert a regular DVD movie to a file that work with the Mp3 Touch. If someone can tell me how do that or give me some link to do it.....PLEASE?! THANK YOU
