Don't know why people have problems with this - but I find it SOOOOO much better than plugging in a usb drive...
1. Install PS3MediaServer
2. Setup "General Configuration" tab to use the correct network card (if you have more than one!)
3. Setup "Navigation/Share settings" (Basically just add links to your media directories in the shared folders bit at the bottom.
4. Save, then Restart HTTP Server (buttons at top)
5. Click on Status - it'll tell you if it's connected to your PS3 (or more correctly, when it's detected an incoming request from your PS3 since it's the PS3 that actually initiates the connection)
Also required (on PS3):-
in XMB navigate to settings, then Network Settings - ensure "Media Server Connection" is Enabled.
Possibly also required:-
Check PC's firewall to ensure it allows the program through.
If you're not sure why it's not working, try disabling the firewall for a min and use the XMB->Video->Search for media servers option.
If you still have problems, it's possible your router is getting in the way somehow. Suggest you go to the PS3MediaServer forums and search for similar problems.
I love this thing - My PC has 2 1TB External drives attached which are shared using this, not to mention my 4TB NAS server (on which i have an implementation of ushare installed!)
The other benefit of all this is that I can watch stuff on my Bravia TV, or in the bedroom on my D-Link DSM510 media player.
Best thing since sliced bread (although PSJB comes in a solid second place - if not joint first!)
