I bought a PS3 as a media server: a central hub that would manage my entertainment. I struggled for days with Windows Media Player 11. Orb solved my problems; however, I ran into issues with it. Broadly, Orb allows users to watch their media from anywhere. Orb is an amazing product! Just not what I needed.
No matter what product you use, you’ll likely have to adjust your OS firewall and your router’s open ports. Luckily, the Google serves up the information quickly and easily. If you run into problems, let me know and I’ll try to help. Good luck and enjoy!
