I think that the other DVB boxes that I have signal widescreen via one of the
pins on the SCART connectors. This obviously isn't possible if you're using a
straight Svideo cable as I am currently.

I believe there may be other mechanisms in use, but I doubt that the graphics
cards manufacturers really give this much consideration - hence Myth shows
4:3 output on a 16:9 display (and vice-versa) through use of black bars.

I've just set my TV in 16:9 mode - this is fine unless I want to use the
image viewer which seems to ignore the aspect ratio setting and assume you
have a 4:3 display. Mplayer seems to do the same, but fortunately Xine does
take account of the aspect ratio.

I should just get around to connecting via VGA/RGBHV, which should make
this moot.

 Is the correct way to handle this to use one of Myth's zoom/stretch 
 modes to stretch the 16:9 source image to a 4:3 output image, then
 use a TV zoom mode to stretch it back? I think that should work.

You might be able to do that, but it would be at the expense of losing
vertical resolution.

The best way to solve it is to add a DisplaySize line to your xorg.conf file
to specify a display size with an aspect ration of 16:9. Something like:

DisplaySize 400 225

Myth will then output 16:9 to fill the screen and 4:3 with vertical black
bars either side.

Only problem is my GUI fonts are now tiny (in mythfrontend, gdm etc).
But that's been discussed here before and so I'll check the archives.

[mythtv-users] widescreen TV out

2005-04-01 Thread Hamish Moffatt
At the risk of repeating a recent thread I'm still confused about
widescreen TV out. I'm now connecting my Myth box (with GF4 440MX) to a
new widescreen TV. Currently via composite but I'll change that later.

My X resolution is set to 720x576. (Same as I used on my old 4:3 TV,
actually). The TV has various zoom modes for widescreen. It doesn't
seem to think that the PC output is 16:9 automatically though.
(I'm not sure what it's looking for as a signal.)

Is the correct way to handle this to use one of Myth's zoom/stretch 
modes to stretch the 16:9 source image to a 4:3 output image, then
use a TV zoom mode to stretch it back? I think that should work.

Our TV networks here also transmit 4:3 material with vertical black bars
added to produce a 16:9 image. I think the same technique applies, with
the resulting image having black bars.

This is only temporary as I expect to connect the PC directly to the
TV's RGBHV inputs pretty soon anyway, and run 1920x1080i or 720x576p or
similar (or both at different times).


thanks
Hamish
