How can I download videos onto my PSP without downloading a software?
FIRST U OPEN UR CLOTH ,,,,,,,,,,,,,THEN U ALSO KNOW.?
If you do not want to download a converter just make sure you download your videos in MPEG-4 format so the PSP can play them. To get them on the PSP check out the bottom of this article http://www.makeuseof.com/tag/put-youtube-videos-psp/ It breaks it down step by step for you. To actually download videos I would recommend using BitTorrent, when you go to a Torrent search engine, just add PSP to the end of your search and you will get results already in PSP format (MPEG-4).
