I've recently figured out how to record on my PSP (finally) so I've been doing some Portable 3rd videos. I'm planning to do Freedom Unite videos, too.
My videos all have sound as well, no annoying background music.
My youtube channel is youtube.com/user/thehardmodegamer
I've got almost 400 hours in Freedom Unite and my experience there seems to transfer well to Portable 3rd.
Hope you enjoy
