I have been using PavTube DVD Ripper to rip movies to watch on my Kyros. I have been ripping them into MP4. Most of the movies are 1GB to 1.5GB. As you can guess, with this file size you can't get too many on a memory card. Anyone know of a better file format to rip movies to that take up less room but still have decent picture quality? Sorry if this is a "newbie" question. I am kind of new to ripping dvd's.
