Your photos seem to show what I would like, except that you're in a
1024x576 window on a 4:3 device.

We're talking about DirectFB and full-screen and output on a 16:9
device. The problem might be either of those 3 conditions.

On a 720x576 physical resolution, I (and also Hugo, I think) would like
the horizontal scaling to fit the entire space (ie. 720 pixels), and
horizontal scaling to enlarge the image to show only ~400 MPEG lines on
the 576 physical lines, leaving ~176 black lines out of the physical device.

I'm not able to take shots and post them at the moment.
