Sorry to be dumb on this - I guess picture scaling is an area of
MythTV I've never understood and I don't understand the implications
of decisions I may make.
My TV's best resolution is 1366 x 768 which isn't 16:9. I can't get a
modeline that works at that resolution anyway, so I ended up going for
1280x768 which was the closest I could get. MythTV seems to like 4:3
or 16:9 resolutions but that doesn't match my TV. So which to go with
- the one that more closely matches my TV's native resolution, or the
one that matches what MythTV likes? What impact on my viewing will my
decision make - will I see a difference in picture quality or will it
be so subtle that is just doesn't matter? And so what if both the TV
and MythTV do some scaling - again, how will that affect viewing
And is it a binary thing - the resolution is either bang on in which
case no scaling required, or it's not in which case scaling is
required (ie close just isn't good enough)?
