OK, so your X is configured at 4:3 (or close enough--1.348659:1), with a 
DPI of 58x44 (non-square).

Therefore, I'm guessing that your HDMI->composite converter sees a 4:3 
signal and assumes it's outputting to a 16:9 display and pillarboxes the 
X output then sends it through to your TV (presumably with WSS?).  Your 
X is configured with 1280x720 resolution.  Any specific reason why 
you're using that and not a 4:3 square-pixel resolution (and, possibly a 
"4:3 standard" resolution), like 1024x768 or 1280x960 or whatever with a 
square-pixel aspect (like 100x100)?  I'd be interested how things work 
with a 4:3 logical aspect ratio (i.e. where the resolution of the output 
has a 4:3 aspect).

If switching resolution doesn't help, you may just have to "un-fix" X 
and lie to it to say you're using a 16:9 display.
