Problem with library files

[Xiben]

When I click on "library" on psp video 9.. none of the files show up, it's just gone. I don't know if I have messed up any of my settings or I might have screwed something up.. but I want to know why it doesn't show. After I convert the videos, it still doesn't show any of my converted files in the library.. can anyone tell me why and how I can fix this? Thanks in advance.
