Just my experience, with my setup -
When my myth box is connected to a tv HDMI port there is an overscan
resulting in loss of some of the picture edges. It is most noticable
when there is a crawler. When connected via the VGA port there is no
overscan at all. I'm pretty certain it is the Samsung TV that is making
this decision based on it being a tv or a pc monitor. I cannot tell any
difference in quality. Most recordings are HD at 1080i and using VDPAU.
Currently I have it connected via the VGA port but have had it the other
way in the past.

The difference between VGA and HDMI is probably quite small. I think 1:1 pixel mapping is far more important for the picture quality.

At least European versions of Samsung TVs have a menu choice that turns off overscan.
It is perhaps not obvious how to do this but on the TVs I have experience with it is found under Setup->Picture->Picture format then choose "Just scan".
