I have tried PSP Video 9,Womble, 3gp, mpeg video wizard,PSP Media Manager, and psp pro. I have several small mpeg files that I have converted to mp4 in order to watch on my psp. most of the files are over 3 MB in size. When converted the file size is 0 mg. I have also tried to stream them all together in order to make a dvd then use Xcopy psp to transfer them but the files were unrecognized. Many of the files have been given the "M4V20001.MP4" name and placed in the proper directory. I know the directory is correct since other videos have worked just fine. What am I doing wrong? If I stream all the fideos in one long file, can I place chapter markers in them in order to forward it to the right section?
