Don’t waste your time fooling around with all the stuff
that people here are shilling or trying to sell you. Keep
things simple.

PSP saves videos and movies only in MP4, and plays
them only in MP4 — nothing more, nothing less. Thus,
only 2 formats are possible for you: MPEG4/H264 and
standard MPEG4.

If you want to save yourself all kinds of headaches and
aggravation, go with the “real deal” that was designed
for the PSP: it’s from Sony itself, and is called “Media
Manager for PSP”.

If you want to know more, here is their website’s URL
completely written out in full, followed by its direct link:
(“mv_CF” stands for “movie compatible formats”)

Install and launch the program.

You needn’t get the url when downloading the vid.

1. Press the triangle button right behend the add botton, and select “Run FLV Downloader”, then “start recording”
Click in the page where the video is playing. The downloader will automatically save it to your hard disk.

2. convert the video to MP4 format
3. then save it to your “videos” folder of psp memory card. If u don’t find the video on your PSP, you can modify the file name to the filename that is supported by PSP, e.g. M4V00019.MP4. The three characters can not be changed, as it is for video on PSP. You may change the five digits “00019” to other numbers you prefer with the list of videos.

Here is the guide
Good luck.
