Which is the way it's supposed to be. A tv is a tv is a tv, not another
kind of monitor. A tv will only display one resolution, the one it was
built for, in one size and overscan, the one it was built for. Adjusting
the overscan or modeline to anything other than the standard NTSC or PAL
timings will result in picture quality degradation. That's why most
tv-out solutions have a much worse picture quality when compared to
dedicated tv-outputs (dvd-player, pvr350 or a H/Q scan converter). I
didn't ever see a overscan regulation on a dvd player, not even the
highest priced ones. Because it's not needed. The DVD player menu is
only about 600x400px so fits nicely into the on screen area, you have
the same possibility with myth, as you discovered and already used. This
is one of the things that lift mythtv above other htpc solutions.

Sorry for the rant, HTH,
