Blu-Ray Disc Player BDP-S550

[gever570]

I've been messing with this for a short while and have also tried to find some information in google and such but still unsuccessfully.So I decided to try my luck her.

I own a SONY BDP-S550 player,I got it connected to the internet with sorta like a "wireless router" or wireless G gaming adapter.I also own a PS3 and I know that there are several ways to transfer files and media through the network with softwares like "PS3 Media Server" and even WMP11/12.

Neither the ps3 media server s/w that I use on my PC nor WMP11 didn't detect the BDP-S550 and I can't seem to get a way to tranfer files from my computer to the BDP-S550 player.

What s/w do I need to use or what settings do I need to configure in order to get this to work and to able to tranfer my HD movies/music/photos to this blu-ray player?

Thanks in advance

Edit:
Even when I tried to transfer some of my files with an external hard drive of 320 GB the player didn't detect it(need to be mentioned that was before I updated the player to it's latest version-if it makes a different at all)
