True, but John Sturgeon wants to take advantage of his TV's ability to
non-linear stretch 4:3 material onto his 16:9 screen.  If we are talking a
linear stretch, Myth can do that well, but no one has written a non-linear
stretch mode.

When I buy a widescreen TV, I am probably going to splurge on DLP since that
technology does not suffer burn-in they way the rest of them do.  I
personally prefer watching programs in their native aspect ratio, and don't
what the picture stretched.  Even so, the ability to output different
resolutions based on the source resolution could be useful.

If the TV's native resolution is 720p, I would probably want Myth to output
everything at 720p.  However, the TV might scale 1080i -> 720p better
itself, so I may want 1080i material passed to the TV unadulterated.
