IIRC there was discussio of an option in the ivtv X driver to restrict
the 'view' onto the framebuffer display or something. This essentially
gave X a screen that was smaller than the framebuffer but fitted onto
the non-overscanned part of the display.
Try the ivtv lists.
This approach won't work with nvidia. I think Myth would need to put the
OSD into a bounding box. Of course *that* would work for both nvidia and
It would be nice to have an xv 'window' that was bigger than the osd
'window' so the video can extend past the visible boundary and into the
overscan whilst the osd is fully on screen.
I have the xv window/overscan set so the video touches the edges but
this leaves small black bars where there's no overscan and the
adjustment isn't as flexible as a monitor (nvidia's driver has no h/v
shift or h/v scale - just 'bigger' or 'smaller')
