half the US broadcast stations will want 720p/59.94, the other half will want 1080i/59.94 For what you're trying to do, you'll need 3 choices for here. 720, 1080 and 525 in SD
H264 is a nice codec- it's processor intensive to make, however. They'll need lots of power in the transcoding farm to make generation of this codec happen in a timely manner.
And you'll want a proxy format of H264 for browsing, low bit rate. Pulling a whole 1080 package to find out it doesn't have what you want, it's a bit time consuming as well.
