Looks like you're setting it to 200,000kbps. Set it to 20,000
In Compressor make sure you set frame size to 720x486 NTSC CCIR 601/D or in Quicktime NTSC 720x486 4:3
Set Audio to Linear PCM.
Note the KeyFrame rate setting of 24 in the settings I posted (as odd as that would seem).

Since Apple automatically sets Profile/Level I'm thinking something about your setting is limiting that.
If this is for Broadcast you want to keep the nonsquare 720x486 frame size and aspect ratio.

DG Chicago only accepts H.264 for HD (DG National is only SD and requires MPEG-2 Program Stream). DG Chicago requires 50,000kbps though and that's exactly what I got despite the fact that in other compression apps the slate and black would have brought down the bit rate.
