I spent multi-hours playing with computer configurations, all to no avail.
I contacted the satellite people, and they stated that game playing was NOT supported due to latency considerations.
Problem: When I join a game on internet (peer to peer or in HL) my call sign shows up in player box 2 times, thus I can't play game because i can't both be ready.
