Some of the exporting formats give you options to adjust the output; some don't. I don't believe that the H.264 format that you're showing on your screen gives you any options. It behaves for me just as it's behaving for you. You'll have noticed that it's in the category of "Native Format (no re-encoding)", which makes sense. Try selecting a different format for export.
It does make it to Westland, but I have to point my antenna towards Windsor to receive it. Since I can receive all of the other Detroit-area signals with a single orientation to the northeast, I generally dispense with TVO reception.
