That's the problem, my PS3 and PC are in the same network, but I can't find my PC via Mediaserver. But I don't care, I've my external HDD and much work to do with Jailbreak and FTP. So no time for movies. But thanks for explaining it.
No, this is to use your computer as a media server to your PS3 (listen to mp3, watch movies,.. streamed from your PC to your PS3) I don't use it in a while but i remember it supports most used video formats and subtitles. And you don't need anything to make it work.. only a PC, a PS3 and a local network..
