I just got a PSP and am new to DVD ripping. I have a 4gb memory card. I've downloaded DVD Decrypter and DVDfab but both converted a movie that is less than 2 hrs to almost 5gb of space. I have seen others with movies that take only 500 mb of space on a PSP that are of decent quality. Could someone tell me how I would go about ripping a movie and getting it on my PSP in a size similar to this?
