Yes, you can use some freeware to transfer your video to your PSP. However, how many file formats do they support? We havent had much luck with them. It seems most of our videos in our collection cannot be converted.

River Past Crazi Video for PSP is the easiEST way to put your video on your PSP.

Intelligent
PSP requires the video to be 320x240 at 29.97fps. Your videos may not be the exact resolution and Frame rate. We resize it and change the resolution for you automatically.

If your Aspect ratio is different, we will handle that as well - either with Pan & Scan or Pillar Box, whichever one is the best way to show your video on the PSP.

All Formats
Built on our Video Cleaner program, Crazi Video for PSP accepts the same wide range of input formats as Video Cleaner, whether it is Windows centric AVI or WMV, MacOSs MOV or MP4, open source MKV or OGM, DV from your camcorder or 3GP from your cell phone.
