Java around the world

i've searched all over the internet trying to find out how exactly to transfer my pc files to my ps3, but had no luck. on my ps3, i already "found" my pc's WMP11 server, but when i open it, there are no files at all. on my pc with vista, windows media 11 already has everything in the library. please let me know if you can help. thanks ps. all my music and videos have not been changed at all or converted. my music is .mp3 and videos are .avi and .mpg
