Every day there are more portable players with millions of users. For them it+s very useful to have a program like Nidesoft DVD to MP4 Converter 3.0 which converts your DVD movies directly to iPod, PSP, iRiver, iPhone and Zune formats so you can enjoy them wherever you are..Of course it lets you select chapters or set options from the original DVD that you want to convert (and thus take up less space) and you can also establish the resolution of the resulting video.
