Videos not working on psp

Okay, so, I put youtube videos on on psp using this download/converting soft ware. Some videos don't work but all the sudden, there aren't ant videos that are working. I tried to put videos on the psp on two different computers now and still, no videos...

work. Whenever you put something on your psp it will show how it's downloading to your psp on your monitor and the psp screen. It does that little back and forth light thing on the psp...=)
But anyway, I've tried it with pictures and those work the right way, but still not the videos. So I've come to the conclustion that the problem is in my psp. Sooo, if anyone else has experienced this and has fixed it, or if anyone has any suggestions it will be greatly appreciated.
Oh by the way, I've downloaded yet another soft ware and converter but the videos still aren't downloading.
Thanks!

Well I know the PSP is very picky about the format the video's are in. I don't remember what format it likes, but if you googled it real quick it should tell you. Also, I believe that your PSP will only play the video's if they are in the Video folder on your PSP.

If you have a friend with a PSP try putting the video on his and see if it has the same issues. If it doesn't something isnt working right on your PSP.
