I've managed to get a sort of livable output. My xorg.conf is below.
The main issue is horrible overscan (I can't see any of the task bar,
and slamming the mouse to the bottom left and clicking brings up the
menu, of which I can only see the last few letters of the widest
lines). I've adjusted the GUI size and set TV playback to match, but
that isn't optimum by any means, since the scaling involved leaves
artifacts. Switching between any of these modes has zero effect on the
output.

Not sure where to go from here. My DCT-6200 outputs a much "narrower"
signal. There is still overscan, but I can use the TV's setup mode to
shift the picture around a bit and see it isn't cutting off all that
much. With the 6200 output, it is cutting off much more, which tells me
the 6200 isn't putting out anything close to the same signal as the
cable box.
