Two problems. First, i have a video that didnt work correctly. I try to delete it. It disappears, but when i reenter the file, it is still there. Second, 2 videos are not visible on the pc, but are visible on the mp3. When i am on the mp3, it says 16 videos. I go through, and when i leave video 16, and it enters another folder, i do not see the missing videos, but when i go back to the 16th video, its there. Video sixteen is two videos at once, if that makes any sense.
