PSP Video Converter

If you are familiar with your PSP, you will also realize that the PSP will not read just any video format. So if you have a nice video clip or two that you want to load into your PSP and watch them on the go, you will need to convert them into PSP mp4 format that it can understand.

One of the best free converters is the PSP Video 9 software.

"PSP Video 9 is a free PSP video conversion and management application. It can convert regular PC video files (avi, mpeg, etc) into PSP video files, as well as manage/copy these PSP video files between your PC and PSP."

I use it personally, and I find it easy to use, and gets the job done.
