I have a 16:9 Sony and when I view 4:3 content I see black vertical bars on
the right and left so I don't think the issue is with Myth itself. If I had
to guess I would think it has something to do with your video card settings
or how you are capturing your data although I think it is the first. You can
use powerstrip to tweak your image to move it over to the left but you have
to have windows to run it. Myth also has the ability to move itself on the
screen but I have never had much luck with it myself. I would definately
recommend using the DVI port for best quality. Good luck and if you need
more help post the output of your /var/log/Xorg.0.log file.
