I've managed to connect my ps3 to the internet using my wireless router, and I'm now trying to share some files from my desktop.
How do I pick up the media I have shared on my desktop though my network? I'm running xp, and on my network places on my desktop I don't see the ps3 as being on the network.

Could anyone please provide a guide (step by step would be wonderful) on how to share files with the ps3?
I called sony and they said I have to have a media server or something?
I have never shared files on my home network before, so I'm a bit of a noobie at this. I have shared the internet with my work laptop, but because of the security settings on my work laptop, I can't add it to my home network.

PLEASE HELP!
