When lurking around I found that MythTV can control zoom and move the image off-center. <BR>

I can adjust the image to make it presentable on different tv types.<BR>

So problem solved.<BR>

The smearing is just something I will have to get used to. Hopefully this will go away with digital connections and flat panels.<BR>
