according to CONCACAF's official site matches will be played at different times, check this out:

<table width="600"><tbody><tr><td width="80">11.2.2009</td><td width="220">Costa Rica - Honduras</td><td width="120">20:30</td><td>San Jose, CRC</td></tr><tr><td width="80">11.2.2009</td><td width="220">El Salvador - Trinidad & Tobago</td><td width="120">19:00</td><td>San Salvador, SLV</td></tr><tr><td width="80">11.2.2009</td><td width="220">USA - Mexico</td><td width="120">19:00</td><td>Columbus, Ohio USA</td></tr></tbody></table>
then i'm guessing national tv could possibly have the US-MEX game as well, still i would say any place with SKY will do.
did a little research, ESPN does not seem to have any of the games scheduled, at least not for CR
