I'm one of the people who started a thread on this about a year and a half ago.<br>

I have this feature on my Panasonic plasma display and *love* it.
Basically, for 4:3 content, the picture is stretched to fill the 16:9
display but the middle 50% or so of the image is not stretched
(much). Since many (most) programs have most of the action in the
middle 50% of the image, this means that the main part of the image
appears largely unadulterated, and yet the full 16:9 panorama effect is
produced.<br>
<br>
Note that for sports, like hockey and football and especially auto
racing, I turn this feature off because those programs often do make
use of the entire image.<br>
<br>
Now the reason I would like MythTV or Linux/nVidia to support this is
that my plasma monitor only supports this special mode in svideo or
component inputs. The vga input only supports 16:9 linear
stretch. At one time I wanted to use the vga input, and hence my
question about whether mythtv or linux might support this.<br>
<br>
When this was discussed last year, I think people were generally saying
that this would be computationally too expensive to implement in
software, and so the matter was dropped. But I still think it is
a great feature, and that there would be value in having it
somehow. On the other hand, I've since gone with a
vga-to-component adapter, so the issue no longer applies in my
case. But if I ever buy a new 16:9 display that doesn't support
this mode, then I would of course be interested in this again.<br>
