I had this documentary on my HDD for some time but for the life of me I cannot remember where I found it. I realize a 4GB avi is up on Mininova but this is a nice small size to put onto your PSP, IPOD, Zune player, various players that like .mp4 files.
Tested on my PSP F4.20 works great!
Quality is about average 6/10 as is audio.
Res is 480 x 272
Hope it provides some entertainment/education to a fellow PSP'r.
