i have dvd movies that i would want to rip, then i it will become a video file after the i rip it. Using the converter included in the r4 ds cd or from the r4 ds website for the latest version, it will convert the file to work on the r4, which ic .dpg. My question is, Will the converter program make the video files sizes smaller? I have a 1 GB micro sd memory card. I want to put more than one movie in my r4. Is there a way i can compress my video files into a smaller file size in a .dpg?
